Need tips and experiences for first time winter camping.

2- 30 pound tanks of propane is a lot you could camp for 5 days easy. What we do is winterize the camper, bring rv antifreeze to flush the toilet. Use bottled water for drinking. We bought a 1 inch foam pad to put on top of the mattress that works great. You can dump the tanks at most sewer treatment plants in town. I agree with sleep in the driveway first. And as soon as you get home wash all the salt off of the camper. Have fun:)
