Being a mechanic and metal worker I might try to do something like a Cozy but lower I don't need all the extra head room, and extra space to try and heat. I'm still kicking around the heat idea, it would be nice but there isn't enough electricity for that, no hot water,and I really don't want exhaust fumes. I thought about a small Mr heater but that might be more than I need. I know I can line the cab for heat and sound insulation so maybe engine heat would be enough on the 1250.
