Opinions on a good quality hitch mount motorcycle hauler

looking to buy a hitch mounted bike rack for my dirt bikes. What’s your experience with the good and the bad out there. Wouldn’t mind aluminum if it was strong but I’m ok with steel too. I’d like to stay below 75# and would be great if it were rated for 500-600#. I currently have one on loan that a friend made and it’s really well made. The only problem is the arm that sticks out for tie downs is like 1/2” away from hitting the bumper on my truck. Modifying this one isn’t an option so I thought it was a good time to start looking for my own.
Edit- single bike not dual bike

 

I have a Versa Haul VH55 RO. I carry my Honda CRF 450X mostly, but here’s a picture of my daughters CRF 100 on it.

I would like some suggestions as well for a 420lb sport bike

 

Check out the Boss hitch mounted rack. Can't post link I'm computer challenged. But I've used one to haul my bike (YZ250FX) worked great. Also has an anti wiggle hitch mounting system.
