It's really funny when folks debate DP vs Gas. Both are excellent. Both will get you from here to there. Both have their advantages and disadvantages. Both are the correct choice for the owners that select them. There simply is no right or wrong in this discussion. The right or wrong is most often found in the floor plan selection.
I don't care what you buy or what you paid for it, but if you end up with an RV with a floor plan that does not work for your lifestyle you will not be a happy camper no matter what you paid for the coach.
Think about it. How many hours do you spend driving your coach? Now, compare that to the number of hours you spend living in your coach while parked. What do you think should be the most important consideration?
