I certainly can not
vouch for this vehicle, but noted it was posted just a couple posts under yours.
My first vehicle was the family's former 'bus' a '78 GMC Van with the 400 cubic inch small block set up for towing. Couldn't kill the drivetrain - even after the rear 3rd or so of the rockers, rear doors, etc. rotted away.
it's certainly not the popular choice, but if it is as described I should think it would do the duty just fine.
