Prettty sure that S15 is a little more than 2700lbs on the road , but not a lot.
Towing that on a trailer is more than I’d want to pull with a conversion van. (Most are older and not meant for heavy towing).
Having a little van defeats most of the purpose of a toad, but that’s none of our business.
Having a trailer to drag, park, unhook etc also defeats the purpose of a little B.
So everything is a compromise. This one is your decision and the meaningful discussion on this won’t be really meaningful because you need to decide how YOU are going to use the setup as a whole.
