Hands down the best vehicle to own for moving pins is a full size Chevy Van. Right now I have a 2001 half ton that works good but my 2001 one ton - that I wore out - was the absolute best. I have both set up with class 3 hitches & trailer brake controls so if everything doesn't fit into the van I just grab one of my enclosed trailers.
As for space in the van - if you are moving standard width machines with removable heads you can actually move 7 of them in a full size Chevy Van - tight squeeze with one head on luggage rack and hand truck on cargo carrier (one that slides into class 3 hitch). When doing that I put cardboard down and slide machines in on their side stacking machines two high and it does work.
Newer fold down head machines 4 is the max in the van with them staggered head first & coin door first side by side two rows deep.
With a 7x14 trailer I have moved 21 machines all at the same time using my 1/2 ton but I wouldn't recommend it. Kind of a heavy load for the poor 1/2 ton truck.
The biggest difference between Chevy Vans and everyone else is Chevy & GMC vans have progressive rear springs. So they ride great both empty & loaded. Other vans ride rough empty but not my Chevy Van - it rides as nice as most cars dead empty or overloaded.
The down side to a full size van is 13 to 15 MPG but other than that I wouldn't own anything else for moving machines!
