If you can carry the tote 1.5 hrs to a camp ground after making 3 trips to the property, why not just carry it home and dump it after 2 trips to the property?
I had a small tow vehicle that I used to tow a 17 ft TT I used for hunting season (1 Hr 45 min). I would leave it at a friends home near property my dad owned. I would pick it up and move it to dad's property when I went hunting for a week at a time them move it back to the friends place before returning home. I dumped the black tank (20 gallon usually almost full) into a 26 gallon tote before taking the trailer back to the friends house. I would bring the tote home and dump it and take it back the next time I went hunting.
Now I have a 28 footer and a bigger truck.
