combination on trailer, tent or hotel for me - in that order
if circumstances were different, I'd have a van and use that
or if you can afford it, motorhome and tow the bike. Reckon that would work out cheaper than hotels - they dont depreciate that much or cost huge sums to run - just 000's to buy in the first place
Note: if you are in a normal van on a cold night, it will be colder than a tent.
yes it bloomin is!! Get it ply lined at least and covering with carpet or similar will help, anything to keep the heat in. Having slept in both, laying naked in a field is probably warmer than a van which is bare!
