does have a spray booth that they use to check for leaks
(Yes ; l actually saw the spray booth and saw a trailer being tested) That being said the first hard rain after picking up our Casita
the bathroom fan leaked. All manufactured products have defects and even with proper testing procedures defects go undetected. I have owned both a 1999 Scamp
16 ft and a 2013 17 ft Casita
Spirit Deluxe and both are fine trailers . The perfect trailer does not exist and even if it did ,I doubt I could afford to purchase it. Scamp
and Casita offer value at a fair price IMHO.
