I purchased a 1993 Coachmen Chevy van. It is beautiful, and low millage too! I was just offered an 28 foot flagstaff travel trailer. Can I pull it with the large engine VAN? Anyone know?
I wouldn't, for a bunch of reasons.
The Coachman is an RV built on the G30 van platform and equipped with the 454 (7.3 liter) engine. For 1993, you probably have the 4L80e transmission although there is a possibility that you have the very similar but older TH400 since that was the year they switched.
A Coachman is itself an RV -- you've got a stove, a fridge, a furnace, probably an air conditioner, and a freshwater and sanitation system. It weighs considerably more than a passenger van or cargo van and that affects the capacity remaining for towing.
Anyway, all vans have problems getting enough airflow for cooling leading to high under-hood temperatures and localized hotspots. Heavy towing makes this worse, and can lead to all kinds of fiddly and expensive failures, among them problems with belts and hoses, insulation, the alternator and other accessories, and the ignition system. I had a 1989 van that had been used to tow a camper by its former owner and I ended up selling it after spending thousands of dollars, cumulative, on minor repairs.
So - my advice - don't try to tow anything heavy with that rig. Occasionally towing a boat or a small cargo van or something is fine.
