Well I just bought a new 21 FBRS Micro Lite unit. We are very excited over it. Two things that I was concerned about after researching them and that was the shower stall would leak over the edge and the other was the amount of Carrying Capacity it had. Well they had just gotten in two units on the lot and they had fixed both of the concerns I had. First of all it had over 2200 lbs Carrying Capacity now and they have redone the shower and it now has the shower like the more expensive units have. It has the designer hard plastic Radius Shower door that rolls on wheels. We are so happy that we waited a few months ..cant wait to get out in it!!!
