I have a 2014 Seneca 37TS, so my MH drive train is the same as yours. I have two vehicles in the stable I can tow - a 2013 Ford Focus ST (six-speed manual) when it is just the DW and I; and a 2014 Ford Explorer Sport (six-speed auto w/AWD) for when the grandkids are part of the trip. Both tow very well behind the Seneca and both are very easy to set up when it is time to go. Both have push button start so there is no steering column lock on either. No fuses to pull or bypass as some vehicles require.
I use a Roadmaster Falcon All-Terrain towbar and use their Even Brake for toad supplemental braking. This combination it has always served me well, both on this motorhome and my prior Class C with a different Ford Focus. Hook up, put them in neutral, install the supplemental brakes, and away we go. I do have a charge line hooked up to both vehicles so the battery stays charged when being towed. The Seneca has 12-volts available at the trailer plug already.
The investment to safely tow a vehicle goes beyond just the car/truck/SUV itself. You have to factor the towbar, tow bar mount, brake and running light wiring, supplemental brake system and its wiring (if you want to be legal in most states and safe IMHO), or a tow dolly if you choose to go that way. Not inexpensive by any stretch, but a Seneca is not the type of motorhome you want to break down at a campsite to go sightseeing or get groceries!
