WE bought 2013 and of course after the Tampa RV show where they sell 125 units in a week and promise delivery to everyone on the same day , well not much gets checked or fixed.
Anyway on the recommendation of another owner we used a sub contractor to do the warrantee and anything serious never got fixed. On a special trip from Niagara Falls ON to HOWE Indiana to the factory they fixed most everything in 3 days. The electronic mobile guy they used who thought he was smarter than me didn't address the furnace properly and the following xmas I bought the part from Lazy Days.
We have finally got some happy use out of it
PS you will be equipped with a Kant Leak control valve for tank fill, city fixture and bypass valve. Do not change from one to the other without turning the water off at the source
Don't give up just persevere it will get better and then you will have one of the best.
