Have just purchased an Avondale 550/4 from my parents. I have a choice of tow car (both within the 85% rule). Land Rover Discovery V8 that is LPG converted, or a Rover 75 diesel tourer. Heart says Discovery, head says Rover. I have over 20 years experience of towing (horse box etc..). I feel embarrased to ask the question but i'm getting different opinions from those "in the know" and those who just think they know. This is an honest post so all thoughts appreciated.
