After doing tons of research, we went with the Wave 3 and have been very happy with it for cold weather camping. We use it to warm up the interior while awake, windows cracked of course. Example: Outside was 24, inside was 60+. Takes about 10 mins or so to bring temps to omfortable, then switch to low setting. Place it where we want. We turn it off before going to sleep as we have a comforter to keep us plenty warm. We have a non poptop 2003 E350 extended Club, all windows . Storage of the W3 is easy, we keep it well covered and clean when not in use. It sips propane. For us, Wave 6 would have been too much. With heat loss of a PT, maybe the W6 would be necessary, or if it is usually sub zero outside. I have not used ours yet above 8,000 ft, but I believe it is good to 10k if I recall correctly. Please do your own checking on this.
Our van is transformer in set-up. Insulation in walls behind stock plastic panels, reflective material facing out glued to stiff cardboard (thermoply) are used for window coverings. Floor is stock carpeting. Issues to be aware of are the moisture build up in colder weather, which we get regardless of heater, but seems to be a bit more with heater, and keeping the element clean. Re: moisture - I just do a wipe down of exposed metal surfaces in the morning. Another great benefit is I am not hauling a heater when summer camping.
