Unloading without supporting the rear-end of the trailer a bad idea?

[ovrszd]

Good habits are imperative for trailer loading and unloading. Being able to load and unload the machine with a minimum of force on the tow vehicle is the key. In a perfect world the tow vehicle would not move an inch in any direction, up down forward or back. I have seen people place a block of wood inter the trailer to reduce negative tongue pressure. Have a set of chocks and don't be afraid to use them.

If you bounce the tow vehicle around enough eventually something going to give, expect it.

Wouldn't you have to block all four corners of the trailer to prevent the tow vehicle not moving an inch in any direction?? Then wouldn't you need access to a jack to get the blocks out from under the front corners of the trailer??

I've never loaded a trailer without causing movement on the tow vehicle. :confused3:

Just an aspiration a target and an challenge to use as much finesse as possible loading and unloading the machine

You don't need them on the front because it's connected to the tow vehicle. They are intended to keep the tail of the trailer pushing down to the ground and lifting the trailer hitch off the ball or actually picking up the tow vehicle's rear end. With rear jack stands you avoid the teeter totter.

Yeah, I was just giving Mike a hard time for his statement that the tow vehicle shouldn't move when loading.

It is a good idea because without it can put a lot of stress on the back of your trailer. It can flex a bit under the weight. It will tear your fenders off over time.

Here are two good video examples together of why you need something under the rear of the trailer.

You could throw a wheel chock between the tires of the dual axles and even if the trailer lifts the tow vehicle's rear wheels enough to lose braking, the trailer won't roll in either direction.

Wheel Chocks for Trucks and Trailers

I use a 16' BP aluminum car hauler only 1-2 times a year to haul my 5,000 pound CUT. Typically I think I should put some blocks under the back of the trailer to keep it from lifting up the back of the truck when unloading and typically I end up just driving off without the support. Any reason not to do this, damage to the trailer or truck? It raises the hitch about a foot and the deck gets within 6" of the ground when all the weight gets behind the tandems. I could almost unload without using the ramps which are not attached to the trailer.

You could keep a section of pressure treated 6X6 or 8X8 pinned on the trailer for safe keeping. Then unpin it and set it under the center of the rear deck before loading/unloading. The only problems with wheel chocks, blocks, etc... is driving off without them. Attached jacks don't cost that much and you won't lose them. You might damage them if you drive off with them down, though. But then you should catch that on your walk-around that you do last thing each time before driving off with a trailer..... speaking of which, I ran over my push broom with both trailer axles yesterday. I swept the winter dirt off my trailer and leaned the broom next to the trailer and then moved the trailer ahead about 10' just to put air in the tires and did not do my walk around. Always do your walk around each time you move the trailer.

The broom survived without a scratch!

The 20' car trailer we bought has jacks on back corners. Work well to support back. They also worked well to change a flat tire. We had a tire loose air just as we were pulling off exit to check load tie downs. We were only stopped 15 minutes, changed tire, tightened load tie downs, jack was very handy. I had a hydraulic jack along in case but did not need it.

I just got a new 19' flatbed with 8k pound capacity (gross). There is a decal on the dovetail that says to support the rear of the trailer for loading anything over 3000 pounds. I've got 4x6 and 6x6 cribbing that I've used but like the idea of jack stands. Like the idea of attached jacks even better.
