My wife and I currently live in Sydney Australia but plan to retire early and hit the road in the USA and see as much as we can. Our daughter lives in Vermont so we can call in now and again, but not wear out the welcome mat. We want to buy a 5th wheel and would like some advice on what to use for towing. I was thinking of getting one about 1-2 years old to save a bit of cash but still be under warranty. Diesel (automatic)is the preference and the 5th wheel would be around 30ft (another topic will be what to buy etc). We would appreciate anyone's help and apologise in advance for all the other questions that will be posed in the future.
