I have lived full time for at least 1 year (mostly more) in the following stick and tin rv's without any problems.
29 ft terry/34 ft terry/24 ft beaver motorhome/35 ft jayco fifth wheel and my current 30 ft keystone and a 27 ft Dutchman about 6 months.
All except the Dutchman worked great. A high dollar alternative to any of them would not have done better. No leaks in Idaho winters and lots of snow/no mold/no aluminum separation or buldgeing and all were used in below zero temperatures with no roof damage.......
Maintained properly, most all rv's will give you reliability even if the manufacturer recommends not full timing in there unit.
