Illinois -- 3 or 4 axle RGN trailer?

Right now I have a 2 axle RGN Trailking TK60MG. I am trawling auctions to find a good deal on a 3 or 4 axle trailer with a hydraulic neck. (I have a regular truck with tandem rear axle and a wet kit).

I know that my quarterly permit allows me up to 120k lbs on 6 axles. It does not say anything about 7 axles and I have not found much info on this.

My questions is how much would I be permitted to haul on 7 axles with a 4 axle trailer. I would suppose that I have to get a superload permit for every load over 120k?

The reason for all this question is to decide if I get any advantage at all from owning a trailer to which I can add/remove a 4th axle. Maybe I should just settle for a cheaper to buy a used 3 axle RGN trailer and not spend anything on the 4th axle option?

Thanks

 

I bought my 2 axle RGN for 12.5k at an auction...

But back to my original question... Would having a removable 4th axle, and not simply 3, axles, confer some kind of advantage to me realistically?

I am in Illinois and this is where I operate also.

 

Thank you. I kind of agree with you and I think that without a Jeep there's no way to load that properly. I would just look for a 3-axle

 

I am a private carrier. I haul my own forklifts, the heaviest of which could be 66-67,000 lbs if I put a boom on it. With forks and not the boom, this forklift is 61,000. I also haul scrap metal or other heavy machinery that I buy or get for free. Last piece of scrap metal that was the biggest was also about 60,000 lbs.

It looks small but it is very heavy. I do not anticipate needing more axles than 6 or 7 at most.
