General observation:

I speced out mine to be a "all weather" vehicle that is intended to be used from -30F to 90F.

That is why the "Sportmobile" top is out --- I wanted to preserve the original van top (though it means no standing up).

Your level of insulation is probably fine --- biggest loss of heat is via the top --- how much insulation does Sportmobile put on?


My vehicle is intended to be operated nearly completely buttoned up --- except for crack in window, or aux. ventilation either via the back window (removed and modded), or via a powered vent cut into the side door rear panel where the window is.

I have concerns that my vehicle do not look like a camper, and can pass for a work truck.


With your camper top, you have far fewer ventilation / moisture concerns.
