It's always interesting to see someone that tries to be macho and crawl up and down without ramps. Nobody is really impressed.
It's really rough on the tow vehicle. The interesting part is when he puts the tow car in gear and finds the shock of loading has broken the parking pall on an automatic, or broken some teeth in a manual.
Or, if you are lucky, you'll see the hitch come off the ball and go through the rear window of the tow vehicle - seen that twice!
My ramps are braced aircraft landing strip plates like they use in soft terrain. They slide between the rails in the rear and lock down. When in stored position they strengthen the rear of the trailer - so they are dual purpose.
And they are long enough so I can load a regular car without tearing up the underside of it. It's surprising how often you use it for things other than your Jeep.
When I carry my lightweight buggy, I use removable shorty angle iron ramps, they are much easier to use. Toss them in the back of the tow vehicle.
