Questions on towing the X with a trailer

[O3X5]

It's been broken down for a month now at work so I'm in the process of towing it back home but have questions.

Uhaul's trailer limit is just under 5,300lbs and the x is around 4,500 but an agent told me it's not recommended because the towing truck doesn't weight enough and the x is too heavy for the trailer. Opinions?

It'd be getting towed by a 2017 f150 ecoboost 4x4, trips about 13 miles.

Thanks

Before it gets asked I have no desire to pay $200 for an actual tow for not even a 15 mile trip so please, don't give me your opinion over it.
