My Overlander has been out on the road for eight years & 35,000 miles now, and we're now starting to experience the new stuff installed during the refurbishment wearing out.
There's one, original, from-the-day-it-was-new problem I never addressed until now that has now been fixed - the Bay Breeze sweating on one of the single beds. For some reason I lived with it; no longer - It was fixed this last weekend.
The Factory did not install any stringers between the ribs between which the A/C is mounted. The unit is mounted considerably closer to the FWD rib than the aft. Settling occurred which left the unit kicked-back looking forward. As a consequence, all the cold condensate collected aft could not drain easily, and allowed sweat to build up.
There is no easy remedy to the lack of support not incorportated in 1967
Jump forward to this weekend, and my bubble-level tells me the unit leans toward the street-side by a quarter-bubble, and aft by a quarter-bubble.
Airstream's placement of one of the condensate drain-tubes on the curb side (LH in the image) of the unit was obviously destined to remain dry. Moving the drain to the aft part of the unit appeared to be in order. Drilling the pilot hole afforded excitment.
I had to wait through almost two cups of condensate before the next step.
The curb-side fitting was relocated, and new copper fitted & painted to drain the works.
Nothing like a good improvement on sixties technology.
