Yosemite, battery, propane, heating, March

Thanks everyone! Keep it simple seems to be a good rule. I seem to have fallen victim to the "my RV will be as convenient as my house" syndrome but is isn't. For example, I forgot that when tent camping we run a small catalytic heater in the tent for an hour before bed and then again when we wake up in the morning to take off the chill. Getting back into the tent camping mentality solves a lot. Heck, sleeping in our RV without the furnace on is still warmer than out tent in March.

Tire chains....dual tire chains that cover both rear tires or tire chains and or tire cables for only the outside tire? Maybe this is another thread question.
