Glad you liked the Redhawk. Like I said before, the addition of the sofa just makes it so much more attractive over the 23XD. I negotiated the addition of the slide covers as part of the sale (also a spare tire and mount) and I'm very happy that I did. I wish I had also included the thermostat-operated fan in the vents but that's a potential future mod project.
The side mirrors give you pretty good visibility and I don't have too many blind spots. I just try to avoid sudden lane changes and use turn signals to give others plenty of warning. I thought I'd like side cameras also but there are lots of forum posts here with both pros and cons. The first true shakedown comes next week with a trip to Disney's Fort Wilderness.
As for GPS/RV, I think I'll try my iPhone since can leave it plugged in with one USB and two 12v outlets in the cab. With a little route planning, I should be able to get by and avoid clearance and weight concerns.
I know this is entirely a matter of preference, but drive the Chevy chassis if your dealer has access to one. I drove both the Ford and Chevy before buying and I liked the Chevy over the Ford. The handling was better, the steering was tighter, the vehicle had a more car-like feel and the Ford felt more like a...well, U-Haul box truck. I thought it was noisier and the doghouse was a tiny bit roomier in the Chevy (I could move my feet between the seat and the engine compartment more easily). The acceleration was about the same for both. The Ford was still a nice unit, but I just preferred the feel and handling of the Chevy.
Good luck with your decision.
