I bought my 2007 X139 used from a private party. They were extremely happy with it and hated to sell it. I did find some things that needed attention and I fixed them myself since it is now out of warranty. The things involved construction, like loose cabinets, no caulking on spare tire holder, no insulation around wiring that passes through the metal frame. These items I would attribute to the manufacturer. Other issues that people complain about, such as furnace, A/C, refrigerator, etc. are not really the fault of Cruiser, other than their choice of appliances. These items carry their own warranty separate from the Cruiser Corp.
Given the fact that my unit is comparatively inexpensive and light weight, I am quite satisfied with the construction. Keep in mind that heavier construction will add weight and cost to the unit and it would not be a less expensive unit. For a moderately used 2007 Funfinder, it has held up fairly well considering the former owner did almost nothing with it.
Bottom line is that I am happy, it is small (that's good), and it is easy to tow (that's good), and reasonably priced (that's real good). I am happy to have it and plan to use it very much beginning in spring. We used it sparingly this fall but spent lots of time putting it up for the winter and learning all about it. If you want a comparatively inexpensive unit and easy to tow, I would speak positively about it, especially since it will have a new 2 yr warranty (most are only 1 yr.) Make sure you have the dealer handle any problems that crop up during the warranty. I spoke to the service rep in the town that I bought it in. His claim is that many Cruisers have minor problems that need to be repaired, but that most Cruiser owners are happy and don't have many further issues after those are dealt with, at least during the warranty period.
My advice is to look it over very closely before delivery and bring it back to have all issues handled as soon as they appear. In the end, you should be happy if you can deal with the normal wear and tear issues that come up from time to time. As with all travel trailers, they need to be examined and caulked and recaulked often to keep them drip free. It's not like the old days of heavy, metal trailers that lasted many years without leaking. Use due diligence and inspect it often and you should avoid many of the problems people have. Remember, it is a less expensive and light weight unit. If you want something really well built and without minor problems, go to an Airstream dealer and check their prices. When you compare, I think you will find the Cruiser to be a fair value. Hope this helps you!
