Cant comment on the Ifor, but Brian James ones are great. Also heard from another guy, Fountain make good stuff.

Either way, IMO best option is a solid non-tilt bed with long ramps. It's lower, drives better and easier to get low cars on and off compared to a tilt bed.

14'6" bed should cover most cars. The 16' models are just huge.

Only one issue with a low bed and outboard wheels/mudgaurds, is if your car is very low you may not be able to get the doors open when it's on the ramp. So check that. Although doubt it would affect too many cars.
