Since my TT tanks are only 20 gallons each I purchased a 20 gallon tank knowing that when the thing is full it's going to weigh about 120lbs. I've never had a problem pulling it from the camper to the truck. The waste dump areas usually have a concrete "curb" running around them so if someone has an "accident" the waste is contained. That curb means I've got to lift one end of the tank over that curb to get the tank close enough for the hose to reach the dump hole opening. If the tank is full it means lifting about 60lbs which I can handle, 42 gallons or half of 350 lbs...NO WAY!
