On the Host, for warranty repairs, you do not have to take it back to the dealer you bought it from.
Host will do some wiggle on prices, but not a whole lot.
On my Mammoth, there was some issues from the factory, that they paid to fix. It didn't help the dealership I picked it up from also made some dumb mistakes (hooked a battery up backwards, which does wonders to a electrical system..). We are in the process of getting a few other things fixed now, that I call 'teething' pains because the Mammoth is a new design.
I was originally going to get a Cascade, but the wife wanted the fireplace, and I can actually use the bathroom in a Mammoth..
