I see that Escape is offering their 7 year "extended" (Platinum Guard) warranty. Looks tempting, as it's pretty comprehensive. I especially like that it includes on-site service for problems that could occur. It's a bit pricey ($2,749...an oddly specific price), but looks like it could be handy insurance against potential issues. I would be interested in checking if it's transferable, as that would be a great selling point should we need to sell the trailer within my estimated 10 years of use (may camp longer, but one never knows health wise).
