1989 Jayco Sportster 8, Upgrade Recommendations

Interesting, maybe I should go the buddy heater full time. It heats its up pretty well. I bought some 1" foam insulation that I line the pop up fabric with which I think makes a big difference. I did buy a Carbon Monoxide detector for the camper just in case. I know the buddy heater also has one kinda. Maybe even remove the furnace and save some weight if I'm not using it anyway. Honestly he told me it was electric only, maybe he is wrong. I'll do some digging.
