What engine would you use if this was you?

true fact. Nothing is final and can change so who knows. I would like to have the drive axle be closer to the rear but I dont want to have a turning radius of a football field. right now Im set at a 307" wheel base but that leaves a whooping 12 feet of rear over hang. So regardless Im thinking im gonna have to get that back another few feet

 

I've already done the math on various configurations and found the sweet spot. Technically since I'm using low weight axles (8k lb capacity) and have them spaced right by the next, I can use the full capacity.

Example. Tandem is 34k per bridge law, even though you could have two individual axles rated for 20k or 40k together. In this case if I were to place a drop right in front or behind a drive axle to make a "tandem" I would still only total in 28k lb capacity which is under 34. Same would apply in a tri axle config. If I was running a 15k or 20k drop, then the maximum spacing would have to be 8 feet from the next axle to be able to utilize the full capacity.

I'm 99% sure that's how that works lol. Technically tho at my configureation that I have built, bridge law formula places my truck at 40' with 4 axles in the 64k lb range. So I'm well with in the limits in terms of length

 

Yuppers. There's places you can get away with it for intrastate travel and such but technically illegal on federal roads. Tennessee is like that with our dump trucks. We can run a quad axle at 80k and be legal but as soon as we touch federal highways, we only legal for 62k or some ####. Luckily the troopers don't bother us unless you are being stupid. Just gotta dodge the scales.

 

Can't be over weight on the steers if they never touch the ground. Big brain time.

But seriously I love it. Weird setups like that is what I like
