Dan & Randa,
Here is a link that shows the back bumper of our 2003 2720 SL with a 2" receiver bolted in place.

This receiver was bought at MCD, the TM dealer on Cape Cod.

It works well but I was concerned about the bumper welds letting go due to the constant up and down motion of the bike rack. The two mountain bikes we carried were securely fastened down with bungee cords and ratchet straps. But the bike rack, with the bikes attached, had to be lowered each time we stopped overnight. Re-doing the bungee cords and straps the next morning became a hassle . . . especially in the rain. We finally opted for a a hitch on the front of our TV . . . a much better solution to carrying bikes. (for us that is)
