This sounded like a strange feature, so I did a Google search for "trailer aid bolt heads bottom"... and this is a well known feature, or issue.
They do appear to be grips. I wouldn't use that on my own asphalt, so I don't know why I would use it on someone else's... and on concrete the bolt heads would probably make it slip more. This comment seems to confirm that:

When trying to pull the trailer onto it....it just slid across the concrete, smashed all the bottom bolts and caved in the sides of it on the bottom.
I think I would try to remove them, if they're just the heads of bolts which have no other purpose.

I agree - with something like this (but not stacked on another device or shim) the trailer is essentially just sitting on uneven ground. A jack which can lower (such as a hydraulic bottle or floor jack, or a ratcheting jack which can slip) certainly calls for jackstands; any device which is not completely stable (which includes almost any jack) also certainly calls for jackstands.

If no one else is having this issue I’m thinking it might be because our suspension is raised to its highest position on the trailer?

As discussed earlier...

The leaf-spring setup has an rocker between the springs which allows one axle to move down when the other one moves up, without any spring compression. This provides more wheel travel and so more ramp height is needed.

It would help somewhat to jack the front of the trailer up or down (if it is not attached to a tug) in whatever direction would lift the tire that you're trying to get off the ground.

According to the specs on that web page, the raised height is only 14 1/8", which would not even reach the frame of a trailer with a 4" tall frame rail and 18" or greater coupler height (the top of the ball is at the top of frame height with most couplers). Based on the strange spec and this review posted on the Harbor Freight site, I suspect that those who find this model works for an Escape 21 probably have an earlier version with 4" more lift.

The blue 1.5 ton racing jack is everywhere, but something has changed and this one has lost 4" of lift capacity from the old 1.5 ton model and is much flimsier.

I am going to order the 5.5", tack a small board underneath and give it a try. Scott

Scott and Lori, in the next week or so I should be moving my trailer about in preparation for a trip to the desert next month, and hope to test my 4.5" Trailer Aid on all four wheels, both on the concrete pad in the back yard and on the asphalt street curb. If I get it done I'll post the results. From memory, I believe I drove up on the passenger side front trailer tire while parked on the concrete pad in the back yard. Cliff, 2015 5.0 TA

I wait to hear your results!

Thanks, Cliff. Like I alluded to in an earlier post I’m thinking because we have our trailer raised (not seeing why suspension travel would change) for our RAM 3500 the 4.5” isn’t working. Interested in your results, cheers. Scott

Two Thumbs Down for Me Too As Used on a 2015 5.0 TA

Scott, two thumbs down for me too re the 4.5" Trailer Aid. I took care of this testing yesterday and today, while hitched up and parked in three different locations, the concrete parking pad in back with a near level surface, the driveway in front with a slight downslope, and the curb in the cul du sac with a decided pitch towards the curb. Only in one of twelve situations was I able to spin the tire, and the clearance was minimal, 1/8" to 1/4". This was the driver side front tire while parked along the street curb. For your info, I do not have my trailer raised, so it appears Brian and Jim were spot on identifying that the different type axle (leaf spring) used on the 5.0 TA as the cause. After doing this testing and observing how the pivot point rocker works between the two axles, I am not confident a 5.5" Trailer Aid would work on a 5.0 TA, at least in all situations. I may try to hang some boards on the bottom of my 4.5", but until then I'll make plans to use a jack in the event of a flat on the highway that I have to change. I really appreciate the heads up for me and others, possibly saving us from a very frustrating situation on the highway. Thanks again, Cliff

Cliff, thanks for the follow up, I was starting to doubt myself. Was wondering if I was paying the price for my partying like a rock star phase of life. Scott

I agree: raising the trailer by either spacers (used with Torflex by Escape) or conversion to spring-over-beam configuration (the raising method used with beam axles on leaf springs for the 5.0TA) makes no difference to suspension travel.
