So I know I'm going to need a set, but I'm a little confused between the two. Both made by Race Ramps, but the Tow ramps are $100 less expensive, hold more weight and they are two piece ramps - which seems easier to handle and store. I saw that the Tow ramps only have a 3/4" tall notch in them to accept a rollback ramp - whereas the Race Ramps have a 2" notch.
Is that it? Am I missing something else?

Thank you!

tow ramps are narrower.

I have them and have no issues with them.
