The only issue was a water damage on the hybrid beds and on the dome over the shower. Both issues are the only issues that I could find on line regarding this model. The leak on the beds are due to folding the hybrid rubber flap incorrectly. The dome leak was/is a caulking issue, that might be fixed already. However I will cut out the bathroom ceiling and have a look just in case. I really didn't like the idea of buying a used trailer due to how easy the walls/ceilings rot. However we knew and trusted the history of this unit. Our neighbours bought it used (one year old) and used it for the past 6 years. The interior was spotless. The dealer offered little on a trade-in due to the leak. They don't want the possible hassle.
So far we have only tested out everything in the driveway, but everything works very well and the kids love it! No leaks over the last two downpours.
Pictures below. The RV is a 2007 Starcraft 185sb Antigua. It is a 18ft hybrid RV sleeping 4-6 people!
I will rebuild my triple-e trailer into a utility trailer.
