Epic tow rig/idea

At only 9200GVW, that is a very light duty truck. The truck itself probably weighs 7000, so not a lot of room for people & cargo.  Also, at that low GVW, it's probably a 6cylinder so not enough power to shove that brick through the air at 65MPH while hauling 2500# of racecar in the back.

IOW, an excellent Lemony race transporter.  Do Eeet!

Anton (X-args) has prety much that same tow rig registered as an RV to haul his Cavalier.  This is it at the Ridge recently after Sparky Pete tagged it.

Do you know what he had to do to get it reg'd as an rv?

Each state differs as to what is required for a vehicle to be considered an RV.  In CA, I *think* you just need a toilet and sink but perhaps an oven and fridge are required.  As you can see from these pixs of a homemade RV conversion in California, what they consider to be an "oven", "sink" and "fridge" is pretty strict.

As I recall, California requires something like four of the following:

Cooking facilities with on-board power source (Microwave -- check)
Potable water supply / washing facilities (Hand-pump sink -- check)
Refrigerator (gas or electric) (12 volt Igloo cooler -- check)
Heating and/or air conditioning separate from vehicle engine (12 volt heater -- check)
Sleeping accommodations (A cot or fold-down will do -- could double as work bench)
110 volt power supply separate from vehicle engine (A Harbor Freight inverter)
Toilet with external evacuation (A portable crapper won't pass)

Your state may vary.

Nice, seems doable, now if it was a bit more heavy duty...

Headache rack would definitely be a must, also this one's probably got 10 more feet on his lol
