I just want to caution the people that use blocks or jackstands on the trailer. With jackstands and blocks, it is still possible to run into problems due to them collapsing or them falling over or slipping off. (anyone ever bend the jack on the tongue of the trailer?) I guess my thoughts are that if there is any slack in the mounting of the jackstand or if the trailer slightly moves (tractor operator hit it just a little too fast?)then there is a possibility that the jackstand will give way, and the trailer will dip, truck will go up, and the ride will begin like it did with JOHN.
As was posted a couple of times (post 17 and 23) having a ramp properly built will make things a whole lot better. The leg pictured on the ramp will allow the rear of the trailer to be supported, which will decrease the chance of the rear dipping and preventing the "ride". This is how my trailer was configured up until recently when I purchased another trailer. The new one uses sheet metal sides to support the leg that was pictured, which gives it even more support. (picture the side of the ramp with a triangle shaped side). While the latest trailer is safer, the ramps are a lot heavier. In the case I have the ones pictured in the mentioned posts, I would at least run a gusset a foot or so back to give the leg a better chance at standing in case the vehicle did move while being loaded so as to not bend the leg. The use of bottle jacks is not a good idea in my thoughts. Trailers will move, bottle jacks will tip over and things will go bad QUICKLY!
Another thing, a problem we don't have much of in Florida....lol, is what is the difference in loading down hill or up hill when the rear wheels of the towing vehicle come up off the ground? Won't the vehicle still move? Yes I realize that the momentum is going forward to help push the truck and yes I realize that ramps will dig in if the rig is trying to back up, but what about on a longer trailer (or shorter tractor?) when the load just comes up on the deck and ramps at that point might glide over the top of the ground instead of digging in.
Great post, glad JOHN is ok and hope everyone else remembers to be safe!
