The dealer re-opened for the season and I got my MH in for the leak repair. They mentioned that they knew right where to look, the brackets holding the awning. Apparently there have been others leaking in the same spot. For those who might be confused, the awning bracket extends up over the top seam to the roof where it is anchored. Unfortunately they used silicone sealant so I will have to redo this when it gets warmer. They insist they ran water and had no leaks. I will look at the eternabond material for a permanent fix.
Unfortunately while I was there they asked if I had noted the frame had twisted. Apparently other units like mine had an issue where the frame extensions twisted after towing vehicles (apparently heavy vehicles). I inquired further and was told the point of attachment of the frame extension is the weak point and needed reinforcement with welded plates. I will monitor mine although I tow a lighter vehicle. I'll consider a pre-emptive fix when the warrantee runs out.
An issue that would apply to many B+ owners is the cab-over dripping morning dew, condensate, and dirt onto the windshield. Mine drips directly onto the middle and when cleaned it is difficult to remove the marks. I tried Rain-X a three times but it seems the dripping removes it at the point of contact. I don't have a solution except adding the vinyl gutter from Camping World. I used it in the past and it does re-direct the condensation that runs down the sides to a location other than the glass. I have about 15 ft of white left over in the garage but I really need black for my full paint 293TS. Any better ideas?
