I've always had a SB and used the 'super glide. We knew we needed a DRW to get the trailer we wanted in the future. Went ahead and bought a F350 DRW. I cannot believe the difference. First of all So much bed space is available when we are hooked to 5th. Gives me a lot of room, even with end bed tool box chest. Drove the truck to Memphis Tenn. from Texas to break it in and see DW's parents. I was shocked how it would make a U turn, and park in the mall. It also rides better. I was always for SRW as I was a farmer, but now realize that the DRW get around better then I expected.
