Did the discontinued Triple E Class C use 12 volt DC tank heating pads or 120 volt AC tank heating pads?
I'll bet that 120 volt AC tank heating pads are the usual type installed by OEMs on new motorhomes. For drycamping in the cold, unfortunately those type tank heating pads suck more battery energy than the 12 volt DC tank heating pads because you must suffer the efficiency loss of an inverter in order to use 120 volt AC tank heating pads off batteries when drycamping. 12 volt DC tank heating pads use energy directly from the motorhome's battery bank, thus eliminating the losses from a "middle-man inverter" taking excess energy from the battery bank.
The tank heating pads in our motorhome are of the 12 volt DC type. Also, tank heating pads cycle ON and OFF - they do not run continuously. We also carry in our motorhome a very small size ultra-quiet generator (no longer available) that in the extreme cold could be left running into the night because of it's quietness to ensure that the coach batteries do not get exhausted from powering both the propane furnace system and the tank heating pads. A modern Honda 1000i generator could provide the same cold weather power as our little discontinued generator.
I may have missed it ... where does it imply or state that the Libero Class model does not have the same cold weather construction as the former discontinued Triple E Class C?
