Marathon does a 6 month warranty.
After I took delivery of the coach there was a lot of stuff I found I didnt like, and since I am a billion miles away from marathon they agreed to let me get stuff done locally.
I know they stand behind it, as I am currently having a bunch of work done on mine at a local prevost authorized shop and marathon has paid for it all so far.
so far they have paid to have my,...
4 chassis batteries
pinion seal
pull air bleeds on all tanks
both rear wheel seals
both tag brake lines
all 8 air bags
front leveling valve
a dozen light bulbs
fan hub and bearing
fan belts
air slide belt adjuster
Granted this is hardly the cost of an engine, but they could have told me to get bent, bring it here to marathon or pay for it yourself.
