My long bed is also a Ram 4 door. It's a shade over 20' long so it won't fit in any standard garage. It has a huge turning radius. In town, I park it at the back of parking lots. I need the exercise anyway.
A huge turning radius? The 98 and earlier Ford's were the worst and the 99 to 2004 weren't much better.
Dave Smith use to have the best prices, I don't know if they still do.
