Found this site while researching an issue with my coach and saw all the owners and great information. We are currently running around in a Tuscany model 4076 I bought new in 2007. Like most of you, I have had some things go wrong but I would like to give credit where due. Whenever a problem happened during working hours Damon/Thor would walk me through things and most of the time problem solved. I have also had great dealings with the component vendors as well. That being said here is a list of problems I have had over the years:
Magnum Inverter went bad-covered by warranty/New or rebuild installed.
Magnum Inverter problems-Had to replace control panel and fett boards $$
Leather sitting chairs bubbling and peeling. (this year)
Serpentine belt (cat 350) broke 25,000 miles. Replaced belt/Idler.
Serpentine belt broke again 32,000miles. A/c compressor seized. Replaced A/c compressor/dryer/belt $$
Fridge recall-They came to me to replace part no charge.
Kitchen dinette light kept blowing fuse. Trace to wire coming through steel with no rubber grommet (exposed shorting to ground).
Front tires/replaced 10,000 miles.
Sewer vents on roof compromised last year.
Paint on front roof faded-Not enough coating.
Paint on front wearing rapidly/plastic coating getting mold underneath.
Side windows fogged up-found great place in Fl to repair
Sink drain line cracked and leaked into lower compartment from slide in out.
The ac/vent/heat/defroster vacuum valves have never worked. Replaced.
Extended counter top fell off.
Auto steps motor replaced.
Latest problem Hydraulic jack self leveling system.
We still love the coach even with all the problems (exception-wish it had a king bed!). We all have to remember when you go down the road at 50-75 mph you are putting your "house" through a major "richter scale event" for hours at a time. Not making any excuses for the manufactures or promoting poor workmanship, but campers are like boats. They are awesome when running great but something always goes wrong in the end...Proper maintenance and inspections are a must.
Looking forward to a great resource here
