What about buying a single axle road tractor?  Rental companies sell single axle day cab and sleeper equipped tractors, no conversion needed.  Ryder Truck Rental shows single axle sleeper trucks for sale on their web site.

Believe it or not the Model X Tesla (pictured in the link) has a tow rating of 5,000 lbs per the Tesla web site, comes standard with a trailer hitch. The base Model X has 670 horsepower, the upgraded Model X Plaid has 1020 horsepower.  Per Tesla it can, indeed, pull a  lighter trailer.  I did read an article about the all electric F150 that tested pulling a lightweight aluminum car trailer with a 2500 lb (or so) car on it and range while towing that load was less than 100 miles if I recall correctly.  No idea what the range of the Tesla might be.

Interesting, eh?
