John: I am in full agreement on a glossy reflective coat atop the roof helping keep the RV cool. I think, though, that insulation would play a real role in keeping the RV comfortable in extremes of temperature. And when the RV is parked in 100+F heat in the desert, insulation will slow the transition from night time coolness to being an oven. I found this link on foam. I am thinking either polystyrene or minicel. http://www.closedcellfoams.com/ And this link on spray on brush on or roll on truck bed liner. Their main point is to rough up aluminum surfaces, which would be a must on my Warrior. http://www.herculiner.com/instructions.html Rolf

Two Blocked: Your points about all sides needing to be insulated are well taken. Perhaps; 3" of insulation on the roof as described. Foam sheets glued down, then covered with white truck bed liner. 1" foam glued to the interior walls. Vinyl faux wood tiles laid down over the existing carpet. Or carpet torn up, and wooden flooring laid down over 1" or so insulation. Add an awning to my awning-less Warrior, and point that side at the rising sun. It is true that even the above would not prevent an RV, parked in the desert sun, from eventually reaching the day's temp. Though, it would surely be a much slower process than with the stock RV. Here's a long thread over at the Burning Man forums about rigging your own 12V powered swamp cooler. It is an interesting read, even if just for the testing that went on and for the evolving design. http://eplaya.burningman.com/viewtopic.php?t=33842&highlight=swamp+cooler John, are you thinking of a larger version of the little ventilation hatches already in place on the Warrior? The one in the bathroom has a electric exhaust fan. A twist handle opens the plastic cover, and a bug screen is at the level of the ceiling. Rolf

Two blocked: I am thinking a good 3" of insulation would weigh less than the AC, and would provide for a more comfortable coach in hot and cold conditions. The AC needs to be hooked up to shore power, and is in my mind of limited utility. WME: Sounds like we have been thinking along the same lines! Were the metal or wood risers used to make an air space beneath the foam? This would seem to leave the roof in a unwalkable state. Would not a person up there crush the spray on foam down? Diesel Aggie: It does look like my Winnebago Warrior has an aluminum roof. Thanks for the heads up on fixing. I will dig into aluminum repair and see what I am thinking of getting myself into. A wild thought, coming from my years as an armor crewman; a hatch! I have wanted an RV with a roof top hatch... maybe a marine source to get one that is very waterproof... I am thinking exterior insulation to leave as much room as possible in the interior. I am noticing how many reports there are of the spray on liner acting as a rather good insulator just by itself. As we travel and camp at times in the desert in summer, I am dreaming of really substantially increasing the insulation on the roof.

Hello fellow Toymotorhomers I have been pondering the thin roof of my 91 Winnebago Warrior. Has anyone tried adding insulation to their roof? I am thinking; - remove the AC and TV antenna, and fix the holes. - cut insulation panels to fit. ( what type insulation? Is there a foam type that would especially lend itself to this use?) - glue them on - spray on a truck bed liner on top to seal it. Does anyone have any experience with this? Would the spray on liner be enough to withstand highway speed winds at the leading edge of the coach? Regards Rolf

Craigslist is great, as long as you follow the ironclad rule. Always always always inspect the item in person. Always. CL led me to my latest purchase, a 1991 Toyota Winnabago Warrior. 44K miles one owner amazing shape. Been wanting one for awhile, and am looking forward to our first trip in a few weeks.
