Don't mean to hijack, but at least I can give a weight related reply.
As I posted in another thread I towed my Datsun 240 (really 660) Z on a Dolly, with combined weight very close to 3100lbs + in the hatch my 50+ tool box, spare parts, helmet, gear, cooler etc. I was amazed how well the Escape did. No records 0-60 but very capable and still had resonable brakes. I knocked down 17.8 mpg keeping it most of the time at or below 70 mph, A/C on the return trip.
I'm really impressed with the mileage towing and have given my standby tow rig, the in-laws Dodge V10, the big ¡Adiós!
