Rig setup opinions

TX for sure but must be an expand - 10' with minimum axle spacing of 5'
NM is a bit less clear - they state 46K but am not positive that they won't permit for more

 

If you do get one make sure it is not a flip 3rd axle as you will have to fight with the permit folks every time to be issued a permit as technically if the flip axle uses shims they are not allowed - see the Caltrans website to find the document that talks about flip axles . A fixed 3 axle that is 48' and has enough neck to use with a 4 axle tractor is going to be a very odd trailer. I need all 13' of neck on my trailer to get any weight on my steer axle with the lift axle down and the I can only get maybe 16k.

 

You will not get the weight you are looking for in CA. As a 6 axle 1-2-3
Best you can do is 20+46+60 for 126 and you are going to be 45-50 empty. If you go to a 20k axle state you will not be allowed 46 only 40

Don't know where you plan to run - just in CA or 48 states

 

Get a 16 tire cozad or Murray and you will get your weight easily and run a 3 axle tractor - then you can always add a jeep. See truck dad's 7 axle pictures

 

Not on CA I would not.

 

If you go the 16 tire route, be advised that the murray "professional" as seen with the D-8T is a 2 rail, wide neck trailer and does NOT accept a jeep. With a big steer axle & long neck it is THE trailer to have in CA. You can load almost anything over the back, put equip. up on the neck, & straddle machines over the rear tires. The "loadmaster" is the 7ax set-up and is a 4 rail trailer 60 ton cap. Very verstile. Get a stinger dolly & you can move 631s, 633s, 637s, water wagons using the full length deck OR the jeep. 33s & water wagons with the main deck, jeep for 31s & 37s. This helps when you think about a second truck, just buy a second neck & you have 2 combos. You can also use the jeep as a very short trailer for those mountain dirt roads. It will take a D-6H easy.

as mentioned in an earlier thread, the newer machines are getting heavier, not sure if the 37Gs will scale on an 8 tire dolly. Cozad builds a good trailer too.
