U-Haul car trailer experience?

I actually drove my Barracuda to the UHaul place to pick up the van and trailer. They helped me load the car on. So we could vet the straps and tricks to get the car on. Drove that combo from Jacksonville Fl to Lufkin Tx. No problem. My family has used them for at least a dozen moves since the 70’s without issue.
Now I don’t think they will recommend loading the car full while on a trailer. Weight distribution is key right? Maybe a small trailer behind her car??? They’ll rent/sell you a hitch for that CRV. Best of luck
