Rear rack for cargo

[MurphyIRE]

I need to add a rear cargo carrier for my Champion 3800 generator.
So my Chaparral had a Lippert RV and Camper Bike Racks - LC243621. It had a 250 pound capacity. It's approx $900 with all the mounting brackets.
I see HF has 2" Cargo Carriers $70-100 for 500# capacity. I know I have to get a 2" receiver mounted to the frame SO, a hitch Approximately 200-275 plus installation WAG $ 350 100+275+350 $725 Your comments!
I know the 2" and rack will reduce clearance off road !
