I have been looking at an older which I re-opened.someone was saying they changed rivets for bolts and dome head nuts as rivets become loose after a while.Also changing the 4 stringers for hard wood one's profiled to smilar shape but would it be stiff enough, Also is the breakage of floor pannel more due to under inflation, thanks for the tip on welding ally will pass it on to the coach builder who will be doing the welding

Thanks for the info as I will be taking to a coach builder I will pass on your info.Also what are your thoughts on replacing the 4 stringers for 2 oak or similar hard wood stringers as I know a good chippy.

I have been told that the rivets in floor pannels work loose may be change these for nuts and bolt with dome heads.

Have you seen this stuff Dura Fix Aluminum Welding Aluminum Brazing Aluminum Soldering & Repair Rod is not sold on Ebay US or Amazon works very well , but ive never used it on Ali that's being in fresh water/salt water, but worth a try.

Dave, we have installed thicker rivets than factory delivered when changing new Z rails from previous broken ones assuming would achieve more rail rigidity. Has not helped a bit due that you can't avoid the hinge, flexing effect on Z rails while jumping, riding extreme choppy seas, much worst with underinflated tubes.

Check if a wooden carpentry could build you one long wooden piece side joiners and forget all about Z rail flexing, will work much better than if counting with 2 per side.

Happy Boating

So, does Honwave sell brand new replacement pannels in UK?
I'd appreciate an Internet address or email to contact whoever does, rather than a phone number. My spoken English is less than perfect (not to mention my ear...).
