Hitch Receiver Question

Hello All,

New to Prius Chat and have found it full of great information.

I am looking at installing a hitch receiver on the back of our 2007 Prius. I was looking at a 2" receiver because everything I have is already 2". Did find one brand with a 2", all others have the 1 1/4" receiver, which I know I can buy the adapter. Both would be about the same cost after getting the adapter as well.

Tried holding the rack up behind the Prius and it seems like it could be close for opening the hatch without removal, all depending on how much the receiver is under or sticking out of the bumper.

I would love to get measurements of how much the receiver of both 2" and 1 1/4" stick behind or out from the bumper. Actually the hole for the hitch pin would be more accurate.

It may be worthwhile getting the extension to open the hatch with tilting bikes. Please give me the brand of your rack as well.

The only 2" I can currently find is by 'Quality S'. Rest are all 1 1/4" (Curt, Hidden Hitch, Draw-Tite...).

Mostly want for the bike rack which is only about 15 lbs (light) and the bikes are under 30lbs each also (3max). I do have other attachments but am not planning on them at this time.

Thanks for all your wisdom!!!
