Motorcycle Hitch Carrier - Need to add tiedown

[msnyder1112]

Hey guys, I'm new to this stuff so please excuse my ignorance.

I recently bought a Vevor 2 Motorcycle Hitch Carrier to transport my EBikes and eventually some other fun toys. This carrier seems to be a knockoff of a brand called Black Widow.
I did a mock run with my 70lb ebike and with the high quality ratchet straps, it seems to be pretty stable.

My only qualm is, the first bike setup, doesn't have a loop to connect the ratchet strap closest to the tailgate of my truck and I'm wondering what is the easiest way to add one.

The skeleton of the carrier is a 2 inch hitch receiver made out of anodized aluminum.
Would bolting in a d-ring cause structural issues or should I just wrap the strap around the carrier and attach it to itself?

you dont have any pics so its hard to tell exactly what you have going on, but i have a bike carrier and a swing away hitch that i use and i know how i use straps with it. i wouldnt drill in a nice anodized frame for several reasons...just use a 2" u-bolt and since the top of it is round, it will automatically give you a anchor point at the gap between the frame and top of the u-bolt after tightening it down and you can put where you need it and change it when you want without popping holes all over your nice frame.
i'd also add a wrap of tape to the u-bolt to keep from scratching your anodized coating.

This is what I got. Notice there is no strap tiedown towards the front, hitch pin side.

You could hook to the safety chain loops at the hitch.

Worst case would be looped around the shaft but I wouldn't recommend that unless you really have to.

I did my test run with it looped over the shaft, it worked but it's less than ideal. I didn't think to use the hitch safety loops but I remember it being tucked in there and am concerned the straps might rub the bumper. Worse case, I can use a U Bolt like grubworm suggested!
Thanks!
