I've been using a Wave 3 since my 99 Grandby was new in 1999 to over 9000 ft. and near 0 degrees in the Grandby, with it's only 3000 btu's when below freezing it will take some time to bring temp. up if it was shut off at night. I've had zero problems with it. Before the original maker sold it to CAMCO you could get the platinum pad replaced, but no longer, keep it away from dust etc. with the optional cover and it will serve you well. I mounted mine below ice box and brought a copper gas line through the storage box to it teed off the line that would go to 3 way fridge. Then seeing I had a rising heat problem with the plastic ice box door, I bolted two stainless steel L channels with a ceramic cloth in between them to deflect the heat from the door. You have to have air coming in and going out. Leaving the turnbuckle door open about a 1/4 and then a corner of one of the top window a jar works fine. I never leave it on when asleep just climb into good sleeping bag. For faster warm up in morning I turn stove top burners on for a very few minutes and circulate with fan, and try not to directly breath the fumes.
If below 7000' I have supplemented it with a Mr. Heater Buddy it's 9000 btu's heat area up fast but uses up little tanks fast, and won't stay lit above about 7100 ft. Because of its Oxygen sensor shut off, which wave 3 does not have. The wave 3 will get inside to about 50-55 degrees when it is 10 degrees outside, with aluminum foil bubble insulation over all the windows, and Arctic liner. Any larger wave mounted here would start to cook the seat cushions across from it. No noise, sips gas and just keeps truckin if kept clean. Most of time above freezing, I only need it on half setting once temp. has come up to a comfortable level. Or you can modulate it with the incoming air at turnbuckle door. BYW mice know how to get to that opening, so I make sure it is shut before hitting the sack... BTW , I see since CAMCO started making these, there are more complaints of the quality, I just ordered a new one for a back up in the case my 14 yr. old one quits, so I will compare...Would be nice if they still would service them, as not only dirt but a load of dirty propane can poison the platinum pad.
