Our trailer, when it was brand new, had a leak in the kitchen drain line, that runs under the fridge and above the furnace (caused by the Bozo that roto-zip cut the hole for the outside outlet) and the water that leaked out ruined the control board of the furnace and caused some of the trim under the fridge to swell.
My dealer shipped me a new control broad for the furnace, over night and he had to order the trim piece, after I gave him the measurements.
Keystone drop shipped an 8 foot piece of trim to me, to replace one that was about 20 inches... I have some spare now
The trim and wood in these things is crap, at best, but it good to have a dealer that is willing to help. They even sent me money to cover my labor for the repair.
