Trailer length and maneuverability

I don't know your typical job site space/ manuverability needs but honestly think you'll be able to deal with most trailer lengths and axle options. Like anything, sometimes you'll wish for a little more, sometimes a little less!!! Any way something else to consider is with a spread on air ride you can add a dump valve to the rear axle, dumping the air from that axles bags shifts most of the weight onto the front axle making it basically turn on the front axle, and act shorter, it also helps save some tire scrubbing, and should only be done for tight slow turns, running down the road with the air dumped can cause damage. Basically the Big advantage of a spread is more weight legally, compared to tandems, I forget the typical numbers.

 

With the weight of your load. 25,000 pounds, you could run with the trailer axles in the closed position. Together like the tandem on the truck. This position you can carry 34,000 pounds on those axles.
IF you spread the axles to a 10 foot spread, you can carry 40,000 pounds, but it is a lot harder on the tires when you turn tight.

 

You make it too easy. I'm glad nobody flamed you.

 

Fixed tandum is both axles close together and the set dosent slide forward or back, fixed spread is seprate axles, nither one slides,.

 

If it says fixed they dont, shouldnt need em to. With a single screw and a fixed tandum alum deck i can put 38 grand on, assuming i can put it in the right spot.....

 

You can buy step deck with one of the axles that slide, If you spread the axles, that allows you to carry more weight on your trailer. If you need the option. 25,000 pounds you should be able to set just about anywhere on the trailer and be legal.
