While surfin' around, I stumbled across another site devoted to motorhome repair & restoration....It's generic and not Barth-specific, but there's quite a few threads about drivetrains/suspensions/appliances that D-I-Y Barthers might find of interest.
Go to:

'Course, the site is not near as classy as the one Dave keeps for us here, but then, Barth owners are used to going first-class, aren't we?

You better be careful with your POSITIVE remarks about Dave, as a COFFEE mug might head your way. hehehe GOT TO LOVE THAT DAVE. ron TOO... in his MONEY-GO, Monaco.
