Block/chock the wheels and block up the back end. That's all you need, backs right off. I've done it without blocking the back end. Just go slow so the trailer goes back down slowly in the front.
I was trying to post a picture but it won't post.
Well, I placed 1 cinder block under each rear corner of the trailer, lowered the rear ramp, lowered the front trailer jack enough so that most of the weight is resting on the rear cinder blocks, put the atv in low & 4WD & I was able to successfully drive the ATV onto the trailer. I didn't even chock the tires & the trailer still did not move!
Now, this will not be the norm. I will be heading to Harbor Freight tonight for some wheel chocks (I will chock both wheels). The point is that it worked with just 2 blocks installed under the rear so I'm sure that with chocking the tires as well I won't have any issues.
FYI: It's a 5 x 8 trailer but it's heavy duty. It has 15" wheels, 3000 lb load capacity, & a 3500 lb axle.
Custom made from a company in Davie, FL.
Thanks for the advice!
