The MH just have 12V tank heater pads which won't help dry camping.
Why can't 12V grey/black tank heating pads be used when drycamping? That's what the 12V version of tank heating pads are intended for ... you just have to have enough battery capacity plus generator capability to make it through each 24 hour day.
For starters, even though the 12V heating pads draw 7-8 amps when cycled ON, they of course are not turned on all the time during their thermostatically controlled automatic cycling. So, for example, about 200 amp hours of deep cycle RV battery capacity (using only one-half of it for a total of 100 amp hours per day) should easily handle the heating pads throughout each cold night. The heated water up against each emptying valve should also keep the tank emptying valves from freezing. Then just use the generator each day as required to both power the heating pads during the day plus charge the batteries back up for the next night.
By the way, IMHO one should never try drycamping in cold temperatures in an RV without good generator capability along and without fresh water tanks and plumbing being fully contained within the heated interior of the RV.
