I frequently travel with a friend who has a DP. My gasser is 38' and about 25K when loaded for travel, including toad. His DP is 38' and weighs about 31K when loaded for travel. I can beat him off the line and can out run him on the flat if I want to be stupid enough to run that fast. He easily out climbs me on hills and gets much better fuel mileage. I have a Ford V10, he has a CAT 360HP. We usually get where we are going at the same time.
I would not let "who can beat who in a drag race" weight very heavily in the purchase decision process.
