Towing the Toy Hauler with a full fresh water tank?

I just came back with all tanks full, about 120 gal. The ride was terrific. Never smoother but I ? the weight on the structure and had no problems. Tires were good,I feel I had plenty of reserve and I had been "camping" in a friends driveway and did not want to dump all that sewrage into his septic tank all at once so it took it home to dump in a muni system. I'd say go for it.
