Towing a Car behind a 5th Wheel

When we full time traveled wife drove the car, I drove the truck & trailer. After figuring the cost of adding to the car, the additional breaking system, a tire monitoring system for the car, a mounting kit installation for the hitching system, the purchase of the hitching system, running the appropriate wiring from the front of the trailer to the rear hitch to power stop & turn lights in the towed car, seeing the local welder to make sure the hitch on the trailer was up to the task of pulling 3,000 lbs or more, I added all that cost up and said, honey you drive the car. Since a long day for us was 300 miles, and then we stayed in a park for 1 to 4 weeks, the drive day was not a big deal for us. We kept in communication via CB radios and she got to listen to her favorite radio station and I got to listen to mine. It worked for 8 years that way.
