Leaks. Every vehicle has a leak or two.
About insulation: I'm using 3/4" foam insulation board for the job. Next time I'll use 1 1/2" board, it doesn't weigh appreciably more but the R-value increase is significant. As it is, when I'm standing down for a bit the Big Buddy has been handling the heat job OK. One burner only if it's above 10F, two burners may be necessary below zero F.
Isn't that a combustion heater? Propane? Isn't there a CO concern?
