West tx in those temps hands down the quick is a 6-8 man tipi, not cheap though.
With wood stove if you desire.
If not wife and I sleep down to around +10 every fall in AK, in zero degree wiggy bags and she is cold natured. We sleep together if it gets colder, but has not so far...
Good ground pad is a must. We just started with the cabela's 3 inch foam pad last fall in AK, its enough to keep us off the ground and insulated so far.
Tipis take no time to set up, Put a few stakes in and raise the pole...
But for me, if I was around a vehicle, I'd just as quickly put the bag in the seat and crawl in... Granted I"m only 51 but I sleep in the back seat of my F350 a few times a year in a good bag in the 20s with never a complaint.
I have done it in the bed before too, but you better have a good thick warm pad under you. Steel truck beds conduct cold really well I've found...
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
