Would any one be able to tell me the weight of a Defender Rolling chassis? I have purchased one from E-bay and wish to use an A frame to tow it back with a Vauxhall Vectra 2000CD. I have checked the Gov site pertaining to towing and it states that an un-braked A-frame is able to tow 750K as long as that is 85% of the curb wight of the towing vehicle. The Vectra un loaded is approx 1450k Any ideas or enlightenment please.
