So I bit the bullet and bought a 1UP bike rack for my 1985. I was using the Jack-It but I was worried I would scratch the window with the inside bike eventually getting it up and down.
The 1UP bike rack was designed for vehicles driving offroad and it is built super strong. It's all aluminum so it will not rust. I also like the way it "lifts" the bikes up to preclude dragging on the ground. So easy to attach the bikes now. Takes about five minutes total.
I purchased the 2" Super Duty model. It's rated for two eBikes. I don't have eBikes but who knows what the future will hold for me.
It comes with the locking hitch pin and as a bonus security measure the allen wrench to tighten the hitch is an antitheft allen wrench.
Biggest negative for this bike rack is the cost.
