Hybrid Tow Vehicles

Flat Tow: 2006 Ford Escape Electric Hybrid - I now have 10 yrs and 80,000 miles towing it behind my 2005 American Eagle 40' Class A motorhome, and have not experienced any problems at all with towing or with the vehicle, just normal regular maintenance items(exhaust, brakes, tires) on the tow vehicle. 
However age is creeping up, as it is also used as a daily vehicle, with 300,000 miles on it now. Any persons with experience or knowledge of newer hybrids that will flat tow??
