Hello and Welcome Fillitup:
I am a bit biased but I will answer as fair as possible. I have a 2001 38ft Alpine and love it, and if I purchased another MH I would get another Alpine. Yes I had some problems with parts not manufactured by WRV but they were installed by WRV. Most of my problems were not repaired properly by the Dealership (now out of business) and I kept taking it back until I realized they were #$*^@! me and WRV.
I found another RV service center that does it right the first time.
Even out of warranty WRV has been very helpful and at times still has repaired or replace items even out of warranty. I have met other MH owners who have had similar problems with MH that were build by other manufactures. I think Alpines once all of the headaches are taken care of you will have very few new headaches, just like other MH manufactures.
Personally you can not beat the ride and handling of an Alpine and Peak Chassis, along the great people you meet in an Alpine.
An Alpine that is a few years old, someone else has corrected the problems, and if you want you can get an extended warranty from Good Sam.
