It also changes your load angle, quite a bit steeper, and when you load on ice and snow, that can make for a tricky ride. I already took an express ride off the trailer once this winter with the excavator.
Personnally, if I had it to do over I'd have gotten a 7 ton over the wheel non tilt. After having a tri axle 9 ton (which was over kill for my operation), I miss the clear span of the deck. The ramps were a pain, but after having tilt, I'll take the ramps. With other material, buckets, tools, chains on the deck, the tilt is a pain. And forget loading two pieces. I haven't tried a truck yet, but I wonder if it will tilt before I can get the rear wheels on the tail.
And you can't beat the hay hauling ability of an over the wheels deck. My 23' gooseneck was awesome for moving anything, I wish I could have hauled it behind the dump truck, I would still have it.
