No, the US really didn't get much back beyond the ships.
However...
What you may be thinking of is reverse Lend-Lease (Reciprocal Aid) where allies of the US gave the US stuff. Canada and New Zealand gave the US tons of Reciprocal Aid (in 1945, I think New Zealand gave the US more aid than she received in Lend-Lease). There were also joint projects that used US financing but allied labor to build facilities. It's Lend-Lease because the US financed it and sent the materials, but the allies in question did their part.
You may also be thinking of Lend-Lease aid to the Soviet Union that was financed by US banks, but was British war material. So, that's Lend-Lease from the US, but it's Churchills and Valentines going to the Soviets.
So, the US wasn't getting back used Shermans and trucks, but her allies were sometimes giving stuff to the US to help.
It was the ships I was thinking of primarily (a bunch of escort carriers and landing craft I think mainly), but I had this nagging thought at the back of my mind there was more than that, but just went a-googling and you're quite right about the rest, must have just been my brain being a bit off, thanks for setting me straight
