My inclination is to avoid this option - feels a lot like an undercoating pitch for a new car. But i thought I'd post here for some expert opinions. I know 'mice in the RV' is a topic that comes up a lot and I know its something I should keep in mind.
Does anyone have experience with this kind of trailer undercoating? Is this a legit thing? Am I better off just using the standard approaches to mice-proofing on my own?
We have a 2019 19erd. There are very few holes in the floor to the exterior, and they should already be filled with spray foam stuff. I don’t think the under coating is needed. We have 20,000 miles on ours so far and the undercarriage basically looks like new.
