We Undercoated an RV and Here's What We Learned

By on Nov 15 2017



RV's and motorhomes are frequently subject to harsh environments when going on outdoor adventures.

We've previously discussed the importance of undercoating your vehicle and how beneficial preventing a high build-up of rust is, and RV's are no different.

Recently, our team took on the task of undercoating a motorhome and we learned even more about how to keep all parts of your vehicle in good condition.

PSC used Undercoating in a Can for the motorhome. This is a wax-based undercoat that prevents corrosion and stops already formed rust from spreading.

Let's start with the chassis.

As most motorhome enthusiasts know, there is what seems to be an unlimited amount of coaches to choose from but only a few chassis manufacturers.

Today, chassis come in various weights and sizes depending on the purpose you need it for. Ford offers several motorhome chassis including Class A, Class C, Transit Cutaways, and Transit Passenger options. The chassis also have different features such as anti-lock disc brakes, integrated rear suspension, and shock absorbing body mounts.

Since chassis frames support other types of vehicles other than RVs, it's important to understand what kind of maintenance they need.

Our motorhome has a Ford chassis that is in great condition and largely corrosion resistant.

Ford manufacturers applied an undercoating to the surface that holds up well and can endure different types of weather and road conditions.

The RV body was a different story.

Our RV is a 2014 Forest River Georgetown with 9,000 miles on it.

A significant amount of rust and corrosion was found on the Forrest River RV underbody.

Any steel element of the RV that was not part of the Ford chassis had rust on it.

It's important for consumers to know the underside of an RV might not be entirely corrosion-resistant. When a surface is rusted, it continues to trap water, will flake, and then continue to rust.

The underside of the coach frame seems to have a normal coat of paint on it without any coating that can withstand the elements. Consequently, it needed to be undercoated even though it's a young vehicle.

Combat RV rust build-up with Undercoating in a Can here's what to look for.

The aerosol can allows maintenance to be quick, easy, and convenient even when you're away on your great escape.

Be sure to look closely for corrosion, specifically on areas where the frame and body are connected. We found a significant amount of rust on the tubular component the RV was built upon.

Further, investigate any mechanical components because they are highly susceptible to corrosion. Don't forget the RV steps--rust protection can increase the motor's longevity.

Keep your RV on the road by keeping it rust-free!
