No, you couldn't maneuver with the tag. Steerable means the wheels steer like casters. That way you aren't dragging them on every corner.

both of the rear duels are drive axles (open diff's until you lock each diff or lock both axles together...ala 8 wheel drive).

the (rear most) TAG axle is weight bearing (or usually it is), I doubt this tag has brakes - but I suppose it could.

lowering that rear most tag would put more load/leverage on the front axle (as someone else pointed out) - so unless that front axle has been upgraded / optioned to a higher weight capacity you could easily exceed the rated weight for the front axle.

Maybe the tag axle is for the mother-in-law quarters

Arrow My thoughts on this.

I would strongly agree with Porky here. I would suspect he is at or approaching the limits for the front axle or tires, a tag behind the drivers will do nothing to help that situation. Being cool is a personal opinion and mine is that this misses that definition. I like the idea of a Class 8 MH to be sure but I'm thinking this one just wasn't for my tastes.

Um, you guys realize that when the tag is on the ground all it is doing is helping keep the rear axle weights legal. The only way the tag will increase the steering axle weight is to attempt to take almost all the weight off the drives. It is way to close (think of a lever) to the drives to add anything to the steering.

It is exactly a lever with the drives as the pivot.

Years ago I drove a truck with a pusher (tag in front of drives) and it would lift 2000lb or more off of the steering axle on a 244inch wheelbase and I pulled a 53ft triaxle trailer that had a tag mounted behind the tridem and it would transfer an easy 3000lbs to the kingpin, a fairly similar dimension to a large coach.

Granted you probably wouldn't max out the tag on the coach l8-12000lb depending on build)) it wouls still put a few hundred pounds on the steer and if that chassis is anywhere close to mine the steers are already at or over15000lbs so not a lot of room for extra weight.

surely adding lift behind the drives will add weight to the steers
