I missed this thread, but saw you posted in another section and we were talking a bit on the class b forum about your 18650 project. Welcome to PF.com. The Carado RVs were getting talked down on facebook and other places, but honestly I like it quite a bit compared to other RV offerings on the market right now. They packed a lot in the 136 wb and even gave you a decent size counter-top in the kitchen and a full wet bath.
Keep up posted on your battery/heater project! I've love to see how that progresses.
