get yourself a coach and convert it,i lived in one for five years ,panel it out in tongue and groove,with loads of insulation,get a wood burner and you will be sorted,if you get hassle,just move it,when they have gone move it back,i used to get everwhere in mine,north yorkshire moors were one of my favarite haunts and the west coast of scotland,you get more hassle of the council in a static,if its roadworthy and got a tax disc ,you can stay pritty much stay any where for a few nights,and then go back to your piece of land ,f**k i wish i still had that bus
