+1 for the Jeep Wrangler (2 door) or Jeep Wrangler Unlimited (4 door) - probably the #1 towed vehicle, jeep even offers a wiring "harness" (plugs in, behind the glove box, no splicing) so that you can connect the coach to the jeep w/out any additional wiring....no need to leave the key in the ignition or turned on (to prevent the steering wheel from locking).
Using the factory harness Im able to connect our Wrangler in less about 60 seconds....2 pins, 2 chains, 1 plug, put the 4x4 transfer case in neutral, confirm the parking brake is off & GO !
