I recently debated this issue with myself, and ended up buying a gas Gerogetown. I was set on buying a diesel coach, but after weighing the pros and cons, I went gas. My reasoning was this. Floorplan was important, as we needed a bunkhouse model. That eliminated probably 90% of the models offered. My price range was under $150k, which basically kept me to a used DP (new Legacy @ $140k was a front runner) or new gas. As we are new to the motorhome scene, not full timing (have a 3rd grader), and our adventures will be mostly limited to summer break, we didn't feel that we would be taking advantage of what a DP fully has to offer. If our child, that's still at home, had been older and closer to college age, that would have given the DP a higher rating, as we would have done more traveling through the school year with just the Mrs and I. That said, we found a floor plan we love, Georgetown 364TS, and was able to get it new for just under $100k. Weighing gas/fuel prices, fuel economy, and maintenance, the difference in price/economy will go a long way for the next several yrs that we own this coach. We are sacrificing some ride comfort, possible economy (fuel price vs mpg), and drivability (maintaining speed on hills/towing), but we like our floor plan and what it has to offer over all others, cheaper to maintain, and when we use it, we are on vacation and can take our time, as we are not stuck inside of a truck for hours on end. All this said, I will end up with a DP when the time is right.
