Maybe. My old Toyota is about 4000lbs (rated to tow 3500 with bumper hitch), the Datsun is 2500lbs. If your tow is the same weight or more than the tow vehicle, you are likely going to have...

My Datsun is very low to the ground, I think the attachment for the tow bar is about 1 foot off the ground, and the truck hitch about 1.5 feet. Enough to notice the truck diving while braking, so I...

The reason the towed vehicle steers behind the tow is the front alignment caster angle, it gives stability at speed. All steered vehicles have this, even bicycles.

AC is very useful when the humidity is fogging the glass. And I don't think the AC is as much a hit on fuel economy as you claim, it certainly does not keep me below 50mpg.
