We have a 2011 Bighorn 3055 RL and have a leak coming out of the wood covered box that you bump your head on when you get into the side storage compartment. Thought it would be something that would stop when we emptied the gray water(thanks trailer gods for not making it black water), but it has just kept on leaking, slowly but steadily. Found a vent stack on top that might have gotten some water in it, but haven't had rain for a couple of days, and it appears to have just started. Is that a metal beam put there for reinforcing? Have looked at all the plumbing fixtures and they are dry, but maybe the lines to the toilet are compromised? It seems to have plenty of pressure to flush. This beam seems to be along the wall of the toilet area, but no telling if that's where the water is getting in. Any ideas?
