Cold Weather Warm Up

You have discovered just how poor the insulation is on RVs. Even ru ning everything full blast you will be lucky to get it to 60.

Last winter prior to leave for the southlands I found all my exterior doors had frozen locks. Got that fixed but forgot the fuel doors also had locks and did not thaw them. At the first fuel station I needed to get it done and was shocked on how long it took. Not only frozen compartments but the locks themselves need attention.

A word of warning. At these temperatures, it is not uncommon for the exterior compartments to freeze shut. It behooves the owner to have a method for thawing them (a radiant heater, for example), or to carry sufficient cords inside the RV or both.

After 90 minutes (5:40 am) the Ambient temperature remains at -18 and the interior of the RV has reached 8 C (46 f).

It looks as if I timed this well so that my cleaning lady will be able to do her magic.

I'm "pushing" the Yamaha to the edge of its abilities. I do this by monitoring the charging voltage from the Magnum inverter--and the output voltage. When there is 13 volts of charging the alternating current is about 115 volts, I'm at the edge.

If I go "beyond" the capacity, then charging voltage drops to 12.2 (useless, at these temperatures). When that happens I reduce the load on the generator.
