Unfortunatly we will be travelling alone but in a place where someone comes by every 20 minutes or so. Plan with pressures in to start at maybe 16/18 psi and go down from there if required. My tyres are 275/70/16 with a highway type tread on them ( can't change them at the moment) and I'll have a pair of Maxtrax, long handled shovel, snatch strap UHF... if it gets too soft may shy away and stick to the easier stuff till I get a bit more experience. Thanks for your help guys. Dan
