Firstly wanted to say hi from me (Michael) and my better half Fran, and not forgetting my 1983 air cooled T25 hi-top monty

But mainly wanted to ask about Devon!
This year we've spent most of our spare weekends around Wales and the east coast as we live in Nottingham, but having planned a long weekend we thought we might head off to Devon? Not definite and we're on a fairly tight budget, of which petrol takes up most of it! So wanted to know if there were any good places to free camp either in north or south Devon? Plus other things to watch out for?
Plus will the M5 be a nightmare Thursday morning? (gulp!)
Eagerly awaiting your most valuable experience from the T25 community

Thanks
Michael, Fran and monty !
