We have done both - pulling a toad and renting as we went (not able to bike those distances!) We would never go without a toad. Here are another reason, quick access to a vehicle in case of an emergency or some other reasons - getting that forgotten grocery essential items, getting to a Dr/hospital/vet quickly, ability to leave the RV in event of a breakdown and the list goes on. Renting may work but as stated it adds up quickly. We like the peace of mind of having our "life boat" behind us just in case.
I agree , if going toad-less, the max is whatever can fit in a standard length parking spot easily.
