Artic Fox 990 & winter camping

Beware of basement temps, even if mfg. claims basement is heated a 2" basement duct is strictly for marketing only ("Heated Basement" - LOL!!)...A 2" duct into the basement will provide almost zero heat to the tanks whatsoever...Get a remote thermometer set from camping world and monitor basement temps against interior temps - this was a real eye opener for me...With a 2' basement duct, I monitored 24dF in the basement while 71dF inside the camper, after which I added a real 4" duct from the furnace plenum...Abandoning the worthless high resistance 2" basement duct and installing a real 4" duct should keep basement temps within 10 to 15 degrees of interior space...
