A 32-footer will provide some interesting cornering situations if you're not an experienced trailer tower. Plan ahead! Also, if it's been sitting for years, be sure wheel bearings and brakes on the trailer are up to snuff before you hit the road. There's nothing like having to do major brake work, or replace a burned-down axle on the side of the road! It's not a good blood pressure treatment, unless you want to raise a chronically low-pressure situation! I spent several hours just north of Bakersfield, California in the mid-summer sun 30 years ago, patching up a burned out hub caused by a bent spindle.
For good towing, the tongue of the trailer should carry 10% of the gross trailer weight. If that squats the suspension too much, fit a load-equalizing hitch assembly, ands a sway controller. The sway control is a good idea, regardless of whether an equalizer is needed or not.
