First a bit of background, I have a rather small 23' motorhome with a 2001 Ford E150 chassis and 5.4L V8 engine. It has an empty vehicle weight of about 9,200lbs and a max total gross vehicle weight of 11,500 making it only able to tow a car weighing less than 2,000 lbs considering passengers and all the stuff you take with you. I had been searching for a small lightweight car to tow but other than a Smart car, there didn't appear to be many. I test drove a Smart but hated it's ride and fuel economy since I expect to drive the towable vehicle for day to day errands as well. I had just about given up hope when I stumbled on a motorhome forum where one guy had towed an 2002 Insight. He mentioned a 1600 lb. curb weight but I soon discovered it was more like 1800, about the same as a Smart. That got me looking and I found a 2001 Insight with only 100K, one owner, and new tires at a Toyota dealer about 3 hours away. Price $5500. I spoke with the salesman on the phone and he took photos of the underside to show what appeared to be a nearly rust free car in upper Michigan. I was able to take him down to $4800 due to unknown battery condition and put a deposit on a credit card. Once I finally made it up to purchase, we discovered it had a brand new IMA battery installed 2 months earlier as well so I was very pleased.
Drove it home and purchased a towbar and baseplate from Blue Ox. The baseplate was a bit challenging to install but securely attached to the octagonal bumper mount frame as well as the aluminum casting attaching to the main frame, so a very secure setup. It protrudes through the grill to attach to the towbar. I installed tail light wiring, brake cable for the surge brake towbar, and a battery minder to keep the 12v battery charged since you need to leave the key in unlock mode to allow the steering to free steer as it is being towed.
All in all this appears to be one of the most fuel efficient, lightest weight towed vehicles available for motorhomes to tow. I have a manual transmission so it is not an issue to tow 4 wheels down. Heading to Florida in the near future to escape this horid winter weather.
