I absolutely concur. Not to mention that if you have CVT transmissions in those CR-Vs you won't be doing your transaxles any favors hauling that much weight around. Inside, it is basically a metal fan belt doing the pulling.
As an example, I have hauled Pearl on a trailer behind a Ford F-150. I know that's a lot more weight than you'll be hauling, but at about 3,500 pounds all in back there, it was about all the F-150 could handle. Drop the weight back there to 2,000 pounds for the Speedster/tow bar and put that behind a CR-V and not only will you have to give up passing anything else for the entire trip, but you have to start setting up for an off-ramp about a mile before you get there because the brakes aren't made for towing and absolutely forget about anything resembling a "panic stop" - You'll just keep on going.
U-Haul trailers are marvels of forethought. They've anticipated just about everything and provided for it in their design, but that makes a slightly heavy trailer, even though mostly made of aluminum (they're expensive, too, but U-Haul never sells them after they're depreciated). They recommend AT LEAST a 5,000# tow rated vehicle (F-150s are rated between 5K and 11.5K towing pounds) that has a gross weight of over 3,800#s to off-set the weight of the trailer/car. It should also have a "towing package" with a hitch AND facilities for trailer brakes (U-Haul has trailers that have integrated trailer brake actuation without need for a trailer brake controller in the tow vehicle, and it works really well - it's called a "Surge brake").
I know...... A lot to take in. So the options are (1.) find a suitable tow bar, borrow or rent an Explorer or pickup as a tow vehicle or (2.) rent a car hauler trailer and F-150/F-250 pickup to haul it safely.
