Any RV'ers around here?

I did the 5th wheel scene first and decided I wanted to tow my classic behind me , coundn't do that in a 5th wheel plus the diesel only got 18.3 mpg towing. So I went to a small Class A (wanted a diesel serengetti 26 footer but couldn't justify the huge price increase between $45k gas and $99k diesel.with same spec's) it would have taken me 20 years to make up the cost difference since I only put 8k a year on my class A right now. But my 28 footer with one slide out get's 9.5mpg and tows the challenger (on a dolly and 10.5 not towing for shorter trips<1500mile )so when I park I look GOOD! and get plenty of comments. since I'm finishing up the /6 dart convertible with all the modern add-ons like air/cruise ect... it will be the towed car (lighter and better gas mileage too!)
