I notice that on a west coast 7 axle trailer. (I.e. murray loadmaster) whenever anything is loaded its nearly sitting over the center of the neck of the trailer.
1. Is this done so that there can be a decent amount of weight on the drive axles of the tractor?
2. Im pretty sure over a 16 tire trunnion your given 60,000lb.. therefore traillers like a loadmaster with a 60 ton capacity should always be at least 15,000 under the mechanical capacity of the tractor + trailer(jeep/well section)
Mexhanical capacity
20S+46D+60J+60T=186,000
Tare weight
20k tractor + 27,500trailer combined = 47,500
Max functional loaded weight
120,000load +47,500tare = 167,500max loaded weight.
3. With that said. If you load your load in sucha way where your load weight is sitting entirely on jeep and trailer with that create a negative effect on steering/drivability?
4. SEPARATELY If you were to load 100k onto this trailer and attempt to move your load with a single frame (5/16") truck with a light front end and/ or moderate capacity drive will it likely damage the truck if you maintain your weights within mechanical limitations on the truck. With a high rear end gear. 4:10
West Coast seven axle configurations.

Short answer would be no. With this setup you don't usually get the big weight forward. Are you considering such a combo? This was my 1st truck with the 87 model Loadmaster. Alum frame, SSHD 4.11 on air track. It did a fine job. Again, with MY set-up I don't think I ever got much over 42K on the drives and that was with a D-9H (56 tons) This 988B put 59,800 on axle 6-7 with the loader tires as close as I could get them to the jeep.Cat sdp, MartinFromBC, Ruthless and 5 others Thank this.
