It's possible to buy a 5th wheel hitch that slides back putting the pin behind the axle with the flip of a lever. It allows you to turn much sharper and get through the tight spot, then once back near the main road, just slide it back forward. A friend has one on his short bed and pulls a 35' 5er/toy hauler. He has no problems getting around. I pull GN's all the time with the short bed. Even Horse trailers w/ "boxed" front ends and don't have much trouble, just need to keep an eye on things when pulling u-turns and backing. I think if I were pulling a 5'er long distances on a regular basis, I'd go with a dually, from what I've read, they are more stable than the SRW as well you're tires will last longer as their temps will be cooler under load. Either way, get what makes ya happy and welcome to the boards.
