Where to rent a jeep dolly or booster for trailer

Has anyone rented a jeep or a booster axle for their trailer? If so, where? Cost? Rental options: as in do they hook the booster to your trailer? If a nationwide service can I drop it off to their location in another state? Finally: just need the option to have an 8 axle setup. Currently I have a 7 axle setup.

 

Of course not. I wouldn't ever try to do that. I was just trying to do a 93k battery all dimensions legal except weight. My trailer is 45ton.

 

My trailer will be scraped

 

Saw some his stuff discussed on this forum. You gotta give it to that Canadian he was creative and did it his way!

 

I kind of understand. Of course I have zero experience and I don't know the nuances. I have read some of your guys posts from 7 years ago and y'all have been discussing this then! All angles have been worked out on this forum and please be patient with me! Don't want to trigger anyone!
