You will hear good and bad about every make/model of trailer. These things are basically built by hand which tends to introduce a lot of variability unlike cars. And just by towing them around it puts a huge amount of stress on them. They are also assembled with a good percentage of the components from other manufacturers like Atwood, Suburban, Thetford, Dexter, Coleman, Jensen, etc. My personal opinion is that the people with the biggest gripes also have unhelpful dealers who don't really care once the rig is off their lot.
So can you get a lemon from CruiserRV? Sure, but the chances of getting a lemon from any other manufacturer are just as good. The best bet is to do your homework up front, bring a checklist with you and go through everything in detail to make sure you know how to operate it and that it works properly when you pick it up.
My experience has been nothing good with my trailer. Probably the majoriity of owners are satisified as well. After all, it's only those that have problems that need to vent.
Good luck.
