Have two questions...
1. ROOF RESEAL - going to work on this and planning to remove all the old Eternabond tape (it's worn, cracked, etc), and all the old caulking and redo the roof and windows. Plan to add new Eternabond Tape and then coat with Liquid Rubber RV Roof Coating (the stuff that comes in the maroon colored tub). Anyone done this and get good results?
2. EVAPORATIVE COOLER - while I'm on the roof, I have what I believe is an evaporative cooler and exhaust fan that does not work. Anyone remove this one? It takes up a ton of space on the roof. Part of wants to just leave as is but I'd also like to get rid of it. Just don't want to have this huge hole in the roof that I now need to patch. Thoughts?
Thanks for all your help. This forum is one of the reasons why I even decided to get an LD. The information and knowledge shared here is pure gold!
Hi Joel S. I wouldn't coat the entire roof with anything. Spot patching just where needed should do. My experience with Eternabond says that this liquid rubber stuff wouldn't stick to the new Eternabond anyway.
The roof vent hole for the 'swamp' cooler is the standard 14" x 14" size. That is compatible with any other roof vent, skylight, air conditioner that you might want to fill that hole with.
The surface on the roof that is covered, doesn't represent the hole in the ceiling. Could this be your air conditioner? Or could it be something that previous owners could have installed. RonB
Removing Eternabond can be a frustrating exercise. Our LD has sections of the twenty year old Eternabond where the white tape covering is lifting. With a good cleaning, another layer of Eternabond bonds well, after removing the white tape..
There is no way I will ever coat my roof with liquid sealant, I did it to my 1983 LD, it was big a mistake, the stuff started peeling within a couple of years, even after giving the roof a proper cleaning, as described in the instructions, before applying the coating. I see no reason to ever do it again, it has few or no benefits.
If the evaporative cooler isn't working, remove it and install a roof vent, with or with a fan. The roof opening should be the standard 14' X 14", the size all RV roof vent use.

You all are AWESOME!!!! A friend is suggesting that we coat the roof with the rubber stuff hence why I am asking. There is a leak somewhere where there was some old Eternabond tape. So I would do well to just remove any parts that are brittle or chipped and retape. No resealing with rubber!
The AC is a different unit than this cooler/fan thing. Most likely it's what you both are saying, that the cover is way bigger than what is actually under it. The inside measurements are closer to that 14"x14". So I will replace with a vent and go on my merry way. Thanks for the advice. If anyone else wants to chime in I am all ears.
Ron, you're in San Diego. I am in Banning (Inland Empire). We camp in SD all the time. You seem to be an expert. I should stop by your place sometime for a full inspection :)
Hi Joel S.; If it is the rec-air swamp cooler, you will want to plug up the water line. The electric needs to be 'safed off' also, unless you plan on a powered vent. There should already be a Fantastic vent fan nearby. RonB
Not an expert even on my own rig, much less someone else's, of older or newer vintage!
