Salsapants, I bought a new 1984 Intervec Horizon on a Dodge chassis. The Horizon was the kid brother to the Falcon. Horizons were on a 3/4 ton chassis and the Falcons were on a one ton chassis and a couple of feet longer. Intervec closed in the late 1990s and the people that had designed and built the Horizons and Falcons opened a plant and built Class C motorhomes named Phoenix Cruiser. We own a Phoenix Cruiser and it is very remindful to me of our old Intervec Horizon. Same designers and builders.
I was cleaning out old files a couple of years ago and came across the original sales brochure for the Horizon and Falcons when we bought ours. They changed little over the years. If you will pm me and give me an email address I will send you a pdf of the brochure. You can find out a lot about your rig in that brochure because it lists a lot of capacities, specs, etc.
