I have the sleeping bag for cold weather but I was hoping to be a little more comfortable then my heavy sleeping bag and Big Buddy heater just to take the frost of my pants before I put them on. I guess I'm hoping to be able to get up in the morning and take care of business without first getting dressed up like an Eskimo, not sure its practical but I would hope I can have more with the trailer then my tent camp.
Not sure I can work solar into the budget this year but I will start studying up on it and have a plan for next spring.
I have covered the important pipes under the trailer with pipe insulation.
Thanks for all the info so far.
