You have other problems.
You need 10% (or more) of the weight on the hitch, otherwise it will wander all over the place unless you drive slowly.
Triple axle trailer, right? 7,500# axles? Tire sizes & condition?
Brakes? Stopping is ALWAYS a bigger problem than pulling.
Have you ever pulled a 10,000 trailer, let alone “estimated .. between 17500 and 22500 lbs”?
Do yourself and everyone else on the road a favor and hire someone with the equipment, insurance and experience. (easiest bet, go to a used mobile home transporter company. They will have the ball hitch on the back of their semi-tractor and are used to loads that size)
I’m not putting you down, I’m just an “old grouch who has been there, done that and scared myself doing it” type of guy. I once moved a 12’x16’ T&G wooded building that I rolled onto a U-haul car transporter using poplar logs as rollers. Lashed it down with come-alongs & chains, then pulled it a mile or so down a level country road at 10 mph using an RX4 Mazda station wagon.
Yeah, I know, “crazy is as crazy does”.

You think I’ve never used this trailer before? How you think I parked it where it currently is?
