I'd do it in a heartbeat. A 3/4-ton ext'd cab short bed versus a dually crew cab long bed, I'll take the dually long bed any day. Plus, you're getting a truck with 60K less miles on it. That's an easy decision.
Just sold my '97 F-350 CC, LB, SRW as we also have a '99 F-350 CC, LB, DRW. Since we got the dually we did not want to use the '97 to tow our 35' 5th wheel. The difference in the stability/ride is amazing.
If the dually is home and I need to run errands, not a problem, I even take it thru the bank drive-thru. Not a big deal, if the mirrors fit, the hips will fit.

For me, it would depend on the difference it will cost you, and if you feel your current truck is undersized. You wouldn't be gaining any power (unless yours is a 3.73 and his is a 4.10). How much does your RV weigh?
The 60,000 miles less on the odometer would be tempting though.

Buy it, but don't be in a huge rush to sell the 250. When you decide which truck you prefer, then sell the other.
X2 Best advice I've seen yet.
I agree! But I'd bet you will end up selling the 250. The dually is more stable, although some will argue, but make the decision yourself comparing apples to apples. Good luck. Big butt trucks are nice!
If the difference in dollars is less than $5K. Do it in a heartbeat.
Above $5K if your happy with what you have stay put.
My comments assumes your current combo is well matched.
The dually vs. your F 250 SRW will be day vs. night in towing performance.

One more thing if I may. If your 99 is an early version, the 2000 will have more power. There are several differences between the early and late 99 thru the end of the run in early 03 for the 7.3. Front brake parts and hubs for one, as well as the turbo and the associated parts for the turbo. I can speak from experience about the early model front hubs and rotors, they are much more expensive. If you buy the dually and plan on keeping it for a while, mods are cheaper and more available.
