Creates a formidable physical barrier combined with tamper-resistant hardware that makes theft too difficult and time-consuming for thieves.
Installs directly onto the frame using existing factory holes—no drilling or permanent modifications required for your RV or work van.
Strategic vents ensure proper airflow, preventing heat buildup around the transmission and exhaust of your hard-working vehicle.
Crafted from high-grade 5052 aluminum for a lifetime of rust-proof protection against all weather and road conditions.
Whether it's your family's Class C RV or a critical part of your commercial fleet, a disabled Ford E-Series van means a cancelled vacation or a halt in business operations. The exposed, easy-to-access catalytic converters on the E-350 and E-450 chassis make them a top target for thieves.
The MillerCat Ford E-450/E-350 2015+ Cat Shield is the definitive solution to eliminate this threat and protect your crucial assets.
A stolen converter means more than just a repair bill; it means a cancelled cross-country trip, a shuttle bus out of service, or a work van that can's make its rounds.
The MillerCat Shield is engineered to prevent this costly downtime. By creating a formidable, custom-fit barrier, we turn a quick and easy theft into a loud, prolonged, and high-risk task. This isn't just about protecting a part; it's about protecting your plans, your passengers, and your profits.
Industry Recognized: SEMA Award-Winning Design & Engineering
How to get the best fit for an E-450 RV? Use a shield made for it. Our engineers 3D scanned the specific RWD frame to create a shield that provides a perfect, vibration-free fit and maximum coverage for the vulnerable exhaust line.
E-Series vans are built to work, and our shield is too. Strategically placed vents ensure that heat from the transmission and exhaust can escape, protecting your powertrain's health even under heavy loads or during long trips.
For a business, a vehicle in the shop is a vehicle that isn't making money. For an RV owner, it's a ruined holiday. This shield is a one-time investment that prevents the astronomical costs and logistical nightmares of converter theft.

Yes. If your vehicle is built on the 2015 or newer Ford E-350 or E-450 RWD chassis, this shield is designed to fit. This covers the vast majority of Class C motorhomes, airport shuttles, and commercial box vans.
This kit is specifically for the 2015 and newer model years. The chassis and mounting points are different on older models. Please verify your vehicle's model year before purchasing.
Our shield is designed to fit tightly to the frame and exhaust line. In the vast majority of RV builds, it does not interfere with aftermarket components like leveling jacks, steps, or tanks. However, we recommend a visual inspection of the area around your converters to ensure there are no direct obstructions.
Due to the size and ground clearance of E-Series vehicles, installation is very manageable for a DIYer with the right tools and safety equipment (like sturdy jack stands). However, because of the vehicle's weight, professional installation is always the safest option if you are not comfortable working underneath it.
No. The shield is designed to protect the exhaust system and does not interfere with access to the engine oil filter, drain plug, or transmission for routine service. It can remain on the vehicle indefinitely.

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.
The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov

Here's why we think you should shop with us at ExtrailAuto.
The wait time was more than I anticipated even after seeing the notification of long lead times. I have to give them props for giving some compensation for the excessive wait time. Having slightly larger holes would help with fitment. Had a hard time getting the front drivers side away from the pinch weld. Eventually had to use washers to add space away from the truck. Need to update pictures and instalation video for the new sliders they are now making
All packing and shipment were great, everything was there. I had to contract out the install because of arthritis, it took them two hours and looks perfect. Zero wind noise at any speed 0 to 100.
Absolutely love my new rack and roam cases. Appreciate the Sherpa crew as well for their hospitality while the installation was taking place.
Fit and finish is excellent. Looks great on the Bronco. No whistling noise at all, some additional wind noise over 60mph but not much different than it was without the rack. Assembly was not too difficult. Instructions and videos could be a little better.
The quality and dedication of the team at Sherpa is evident from the very first interaction with them, and is further proven in the product itself. This rack is well engineered, easy to assemble, easy to adjust, and holds up incredibly well with no loosening or rattling or shifting (even after over 200 miles of driving on poorly maintained roads). Currently operating with approximately 180 pounds of gear mounted on the bed rack and no issues at all so far. I expected the vibration to work the bolts loose over time, but every time I check they're all still snug. My only regret is that I didn't pull the trigger and get this rack sooner.
First of all, the team at Sherpa is full of passion for adventure and that passion shows in the quality of their products. This roof rack looks incredible and surprised me with it's sturdiness. No loosening of hardware, even after weeks of driving. Currently holding approximately 80 pounds of gear for everyday driving, plus an additional 110 strapped on top during a camping trip (and I even stood on top of the entire loadout). No warping, bending, twisting, or slipping. The fact that this matches the bed rack perfectly in height is the icing on the cake. Easily serves as a tie off for a tarp, rain fly, hammock, or whatever you need. Perfect for modular campsite setup and quick teardown.
I bought the Sherpa Crestone rack for my 2024 4Runner TRD Pro. Incredibly well-made and excellent design. Spend the extra , to get best roof rack in the market. You won’t regret it.
This is our first roof rack that we are going to use to put a RRT (roof top tent) on for back country trips. Well-built product that came with all the nuts, bolts and washers to complete the installation. Took about 1-1/2 to 2 hours install the rack. You will another person to help place the racks on top of the Jeep for final install. Overall, a great, well-built American product
Install was super easy. The quality was great. Customer service was quick to respond to any issues! I’ve already been getting compliments on it and what brand it is. This will be great for camping this year!
This is on my tundra absolutely solid rack looks fantastic extremely modular, which is why I went this route. I can use the whole rack when traveling and over landing then rock the chase rack only when the rest is not in use, I actually use the recovery traction board mounts for my shower room set up, which works amazingly just relocated the board somewhere shown in picture keep innovating TUWAand I’ll keep purchasing.
Good looking cat shields made of stainless steel with cooling holes. Priced well, easy install, no issues. Would buy again.
Great service from their staff. Robert help me through all the process with a request I had, he responded all emails in a timely manner and provided great help.
We received it within 3 days and installed the same day. Great awning and very well made.
the tent is very nice, comfortable and roomy.
Following the instructions was fairly easy. Its better to have second person to set it up. I really like the tent and the support that from ExtrailAuto. Really recommeded! Thanks

High Quality , great fit. Look awesome.
Sliders look and fit great. Pretty simple and straightforward install however, the install video did leave out some key details and extra non-applicable hardware made install slightly confusing.
My new Rock Sliders “Rock!” I love em’ the fitment was perfect and they look awesome on my 4Runner TRD-ORP!
Had a few issues at the beginning with some missing nuts in the package but that was easily rectified with a trip to the hardware store. This thing is built like a tank, and it's been rock solid heavily loaded over some very rough terrain.
All packing and shipment were great, everything was there. I had to contract out the install because of arthritis, it took them two hours and looks perfect. Zero wind noise at any speed 0 to 100.
Great fast shipping. Robert was great and helpful
Fit and install as advertised
Nice product. Wish the step was flatter. On the large end I drilled and taped two more holes on the outside edge to pull it down better. After that I’m very happy with them.
Nice, quality sliders that are straightforward to install. They look good on the truck and are very functional. That being said, the one negative was the long delays on shipping and delivery, and communication was less than optimal to say the least.
Love the easy install and videos!
