To answer the OP's question though ... the day after the warranty expires .... you can expect everything to fall apart!
Respectively disagree with this! :B
There are thousands of RV'ers on the road with older units with original appliances still working on.
My first MH I kept for over 8 years. The only thing I had to replace was the water pump. and that was because I did not winterize correctly and the water froze in the pump and split it.
If you keep your RV cleaned and maintained from the outside very few if not anyone can tell the age of it.
I look at it this way routinely cleaned and maintained RV, if an appliance goes out, replace it! The price of 'any' appliance in any RV is a mere fraction of the cost of buying another RV.
Over time I can replace all the appliances and never even come close to the cost of the taxes on a new RV. :W
I don't want my money tied up in buying new depreciating RV's. I want the money to travel and party! So popping for an appliance or repairs once in awhile is no problem for me.:B
