Hello! I'm a new member looking for some opinions on towing. I have an 88 Chevrolet r20 suburban (3/4 ton). It's a 454/th400 combo. Not sure on the rear gear as the speedo reads about 10 mph off at 60 so some previous owner has tampered with the rear gear I'm sure considering it use to haul a travel trailer back in the day for a gentleman in the air force. Assuming I replace the 33 year old leaf springs, brakes are in good working order, etc etc do you think it would tow a 8k travel trailer safely at say 60-65 mph with trailer brakes. I plan to install a Firestone airbag leveling system on the rear as well. The factory hitch says it's rated for 10000 GVWR with a weight distribution hitch. I don't see a GCWR anywhere. Trailer specs are 36ft, Dry weight of 7756lbs, with a hitch weight of 942lbs.
