For whatever it's worth, I recently posted this comment on another Cruiser thread:
I've had two trailers made by Cruiser -- a 2003 Shadow Cruiser T139 and then a 2012 Fun Finder X139. Both of them were great trailers, able to handle gentle off-pavement towing. (Slow speeds on rocky roads.)
Cruiser is a good brand -- not the best, though. I think that Lance's newer trailers are higher quality. But for the money, the Cruiser products are quite good.
To that, I would add that we have a total of 150,000 miles of happy towing experience with Cruiser products. As always, your mileage may vary!
