IMHO....not for a trailer. MH maybe.
Does the coverage include appliances, tires, electrical, running gear, leaks, water damage, clearcoat, vandalism, road hazard?
Check with your TV insurer, see whats covered under that policy. Most all of the non AS equipment carries a better warranty than the coach itself.
I'm not aware of any aftermarket policy that will cover mistakes made at the factory.
Notice the fine print at the bottom of the page, they don't advertise or spell out the "service contract" or what the exclusions may be. http://www.rvinsurancesolutions.com/...e-TTrailer.pdf
Do the research weigh the benefits carefully.
After 30 some years in the Auto field, most of these "contracts" aren't worth the paper their wrote on.
