Will be pulling the trigger on my first wheel house with in a week or so. Just have a couple questions and concerns to run by some of you. It is a 2014 Salem ice cabin, 24' with 8 holes and a closed off bathroom area. It comes with a 20,000 btu forced air heater and 2 20lb. Propane tanks. The hitch weight is 575 lbs. Dry weight 3997 lbs and gross weight is 5655 lbs. I realize all ice is different but with a single axle how much ice would you look for before pulling it out onto the ice? Also on average temps ( which I realize we don't have) how long would 2 20 lbs tanks run the heater? Also anything else a first time wheel house owner needs to know? Thanks
