I think adding a rear heater versus insulation versus partition (even if makeshift like a blanket) would depend on how the van will be used.Yea insulation isn't the best from what I've heard. I'm not sure if its best to do a whole project to get the heat working better, or if hanging a blanket is just easier for the comparable cost and effort. I'd welcome people's solutions.
Diesel heater?If you look at the Ducato camper sites, there window insulation kits for camping that are out there.
Personally, I think I will get an Eberspacher heater for the back. I won't need a/c since I live in the NW.
I guess it depends on the level of your finish. My van is a contractor van that I insulated with Hein's Thinsulate...everywhere including ceiling. It's been from 8 to 15 degrees earlier this week and it definitely takes a while to heat the van up with the fan on the higher speeds. It will get there but it takes a good 20 minutes or so minimum, but with some patience it gets there. It doesn't get "toasty" for sure but acceptable enough. I couldn't imagine it without the insulation, no way would it ever get warm in 8 degree weather, nor 20 for that matter.I was wondering the same thing.
How is the heat in the winter with no partition in these?
