We bought a used Fun Finder by Cruiser -- used it for six years and sold it for a good price -- bought another one used. They are good trailers -- not perfect. We had the same low point drain issue -- we moved the pickup for the pump and also put a strut under the water tank to keep it from sagging. Check out the links in my signature to find out more about the trailer and about our travels, if you'd like.
I do not think Cruiser's quality is much different from any other brand. Thor recently bought the company -- they have a good reputation -- so we will see what happens.
Make sure your dealer gets good reviews on Yelp -- if there are warranty issues, you want someone who is concerned about his reputation and will go to bat for you.
By the way, we would buy another Cruiser product, if we were in the market for one.
