Re: Which RV do I want? Why are you worried about mpg & cost of fuel. I was in the UK this spring & saw the prices along with the exchange rate. What you need is a 40' DP, Get a older model that has been taken care of. Have it shipped back to the UK & drive teh UK roads!! I just purchased a 10 year old, 41,000 mi. DP. It is as good as a new. Just got home from a summer trip of 9,000 miles. I have had 3 new RV's in the past 6 yrs. Believe you me, they were all a pain to get all the bugs worked out. Take your time. There are lots of good rigs, also there are lots of JUNK. GOOD LUCK!!!
