JFXG-Right, GS is an independent insurance agency. The actual guarantor is Crossroads RV. I did purchase the consequential damage rider.
Interesting enough, all my covered claims have been for the coach portion of our MH but two, one was for the Wabco compressed air plastic purge valve being broken by (I assume) a rock, the other was for a cracked front hubcap (forget the brand) for the wet hubs.
ramjets, the 18 yr limit is an extension of my present ESC. The mileage limit (I think, is 82K) I'm a long way below that @ 43K.
motor7, they will use POR15 or similar product on that rusted compartment only because it is totally enclosed in the underbelly. The frame and underneath side appears sound, with nominal rust expected on a 17 yr old MH.
The black tank never leaked when purchased in '13, nor until last summer when I used a home-made wand to flush the black tank with high-pressure (110psi) water. I could see dried TP on the tank floor, it wasn't bothering anything, but my OCD wanted it gone.
