I have no experience with the Envoy, but I'm sure GM gives it a tow rating. Is it higher than the weight of the 22' Argosy?
OK, did a quick search and found the Envoy has a towing capacity of from 5000 to 5300, depending on equipment and year.
Did another search, and a '75 22' Argosy weighs 3730 lbs.
