It is actually a question only YOU can answer for YOU!
I tow the truck four down, using a telescoping Roadmaster towbar.
I tow the PT Cruiser on a dolly.
I towed Jeeps for many years with a fixed-arm adjustable width A-frame towbar.
to get ready to go with the truck:
EDIT: I forgot the important FIRST step, which is to install the towing brackets on the front of the truck, install the lock pins and safety pins, then pick up the towbar and set it on the brackets and install the lock pins, and THEN:
1. Move the truck to the back of the motorhome, and park it within the right distance from the hitch.
2. Unfold the towbar, release the telescoping arms, and (if the distance is right) drop the hitch on the ball. If the distance isn't right, move the truck or the motorhome, your choice. when it is right, connect the hitch.
3. connect the light harness to the front of the truck and to the connector on the motorhome. tie the harness to the towbar arm.
4. connect the safety chains to the motorhome.
5. Put the transfer case in NEUTRAL, start the truck, and run it through the gears to verify the T-case is REALLY in NEUTRAL. Shut off the truck, put the transmission in PARK, and the ignition switch in OFF, NOT LOCKED position.
6. drive the motorhome 20 feet or so, then stop and verify that the telescoping arms on the towbar have locked.
7. Get on down the road.
for the PT Cruiser:
1. Bring the dolly to the back of the motorhome, using the handy little Harbor Freight trailer dolly.
2. Drop the hitch on the ball.
3. connect the lights and safety chains.
3A. release the latch to allow the table to tilt.
4. Load the car on the dolly, verify that the table returned and locked.
5. Install the tie down baskets over the car's front wheels, tighten them securely, and connect the safety chain.
6. Drive away.
7. After 10 or 20 miles, stop and check the tightness of the wheel baskets.
Only YOU can decide which is "BEST" for YOU!
Good luck.
By the way, the PT CAN be towed four down, with a lube pump. In fact, it had a lube pump installed when I bought the car. I do not WANT to tow it four down. I do not trust the lube pump. They have been known to fail. The dolly will not fail and ruin the transmission!
