Agree. But it is pretty darn stable, so there’s that. And the 12-28 does get you appropriate heights for bed and standard table.
]]>Sorry I missed this post, Stewart! These can *definitely* be replaced, and I would say the level of damage would dictate if they can be repaired. I have bent them back into shape on many occasions. Just be careful to note if the damage is affecting the worm-drive rod for ease of lowering/retracting. Also check to be sure the mounting holes have not been damaged (bolts/screws pulled out so that they won’t “grab” back in). If that has happened, simply drill new holes instead of using the old ones.
]]>Sorry I missed this last YEAR, Eric! Information probably won’t be useful to you any more, but I’ll post if for others who come along later. I ended up using the Carter P4070. A lot of people use this one, and I stand by it as well. This is a “low/regular pressure” unit that won’t work with electronic fuel injection (EFI) that require much higher pressure; it’s for carbureted engines. I will note: I purchased my first one from Amazon, and it did not make enough pressure. The seller said it was the “Carter Store,” but I always feel like there is less quality control and grey market/returned units when purchasing from Amazon. Ultimately I finally called Carter direct, spoke to a very nice lady, and was sent a brand new unit that works perfectly. I think Carter is a great brand, and I always love when you can speak to humans “old school style.” For blocking the hole… I found someone on ebay selling milled billet stop blocks that are made for our engine and simply bolt back on using the original pump bolts. I believe I used some liquid gasket maker around the edge before bolting on to seal it up. Hope you found the right info. and your electric pump has been a success!
]]>Part two is linked at the bottom of part 1! ;-)
At this point, I have created many Airstreams using the information in Part 2, and feel confident in this “4 season” solution. The thermal gap on the ribs is key for summertime, and getting everything sealed up tight makes winter possible.
]]>The two sides of that rib won’t come in contact with anything that would transfer heat/cold. Heat/Cold will transfer from the outside metal skin, through the metal rib, and through/to the metal interior skin (where all three of those materials are in direct contact). Lining the rib with a thermal barrier (like foam) on the surface reduces the amount of heat/cold transferring from outside to inside. The sides of the rib should only come in contact with insulation or air, so there shouldn’t be any reason to line the sides with anything. If the worry is cold/heat radiating off the sides of the rib, there should be minimal concern with that issue (especially when the walls are filled with insulation). Surface area is a huge contributor to temperature shifts. If just the ribs (minimal surface area) were heating up, it wouldn’t be much of an issue, but since that heat (or cold) is then transferring to a giant surface area which then radiates that unwanted heat/cold, it can really alter the interior temperature of the cabin.

Eric
