I owned a FunFinder 210WBS for almost 4 years and ~48,000 miles.
Had three problems with it...leaking tire (picked up a screw outside of El Centro, CA, obviously not a CruiserRV issue), leak around front window (an inherent problem with front windows and why many manufacturers no longer offer them; re-caulked and no further problems) and my water heater died (loose connection under a wire nut). Great trailer and I'd still own CruiserRV products if they sold 5th wheels.
Now... Will you have a problem with one? Probably, I don't know of any RV that doesn't have a problem or problems, take time with a PDI and look for potential problems before hooking up from the dealer. Most "problems" can be caught early enough to not become a major problem with due diligence in spring and fall inspections. It is inherent in the product and what we as a buyer are willing to pay for, but, unfortunately price point is not a good indicator of quality as there are owner's of Prevosts that have issues with them as well. Top dollar or bargain basement, they all have the propensity for having problems. Personally, I would buy CruiserRV again if I ever downsize from the 5er or if they start building 5ers and I'm looking for trade.
