An auto car on a tow dolly?

Still waiting on offers for the jeep, nothing yet. It decided to throw a couple curve balls in the meantime that'll complicate selling it, the AC blower and brake lights decided to stop working. Checked the fuses, they're fine. The regular taillights come on with the headlights, so the bulbs and circuit are still good. Whatever it is, it's also tripping the Check Antilock light.

In the meantime, I'm making sure my pickup is capable of handling the dolly weight. I might've forgotten to mention my bumper has a receiver hitch, and according to guys on the trucks forum it should handle the weight. It does have the 1-7/8" ball, but I picked up a 2" ball for it.
