To Add My 2 cents!
From my experiences and from what I have read on this forum for the past 2 years, WARRANTY of any kind is a JOKE.
It really does not matter what the problem is there is no warranty, my experience:
-dealer unwilling to provide any warranty after the first year (read into that season).
-dealer unable to provide timely repairs to anything unless of course you are looking at a January drop off, if you have an issue it is 3 - 4 weeks wait to get the unit in for work, where we live that is almost 1/3 of the season.
-manufacturer, take some pictures and send them in, they will make a decision! Then what? That is your issue, part of maintenance, out of warranty period, take it to the dealer (see above)
In my experience do the work yourself, which allows you to see exactly how the unit is put together and learn system operations.
Our axles were bent (new unit 2012 (purchased in 2011) used summer of 2011 & 2012 at the end of the season it was noted that one tire was extremely wore out on the inside after only 5000 miles. As winter was arriving I elected to put the unit in storage for the winter (2012) my mistake. When I got the unit out I took it into the dealer for "investigation" (the manufacturer required pictures and measurements). The result was: yes the axles are bent, warranty out of time range, but as good customer relations they will provide new axles, no charge, but will not cover install or any replacement tires or wheels. Sounds great.
Delivery 3 - 4 weeks.
OK what about install? Dealer will allow an appointment to be made AFTER the axles arrive and at this time it would be a 3 - 4 week delay getting the unit in for the install which will only take 1 day. A total of 6 - 8 weeks, GREAT.
I took the unit to an axle shop and had them assess the issue, the axles are bent, they will not straighten them as the side walls of the axle tubes are so thin the shop is afraid of bending, cracking, crushing the axle tube, they recommended new axles from a different manufacturer.
Decision new original axles with the same thin side-walls with a 6 - 8 week delay, I didnt feel safe driving the unit or wearing tires out and having to replace them every 5000 miles. OR new replacement axles built better, superior axle, with only a 2 week delay, the difference is: inferior axles I pay the install, superior axles I buy and pay the install, the only difference is I pay for the axles, and the time involvement.
I elected to buy new axles, safety, peace of mind, PLUS we didnt loose a whole season and didn't have to cancel our major holiday plans which has reserved camp sites paid for already.
