I would highly recommend getting a NGB, its a lot less hassle. I had a GB (with the cylinder) it did the job, but I had a few bad issues. A GB will do the job, but you have to be more aware and patience. The one I had was a PITB to hookup, you had to be almost perfectly straight, to lockin. Most of the NGB, newer styles have lineup pins, that get you almost perfect to lockin. The NGB is easier to get hooked up in soft areas, you might have to think ahead and put boards under the trailer first. Mine had the pony engine, but it never failed, but a friend of mine had his fail twice on a busy road, trying to load his equipment. It wasnt a pretty picture and most of your friends lowboys, wont hook up to yours, so make sure you have a wet line, because that stupid pony engine, will never quit, unless you unhook LOL
Good Luck
