Yes I noticed that also but after I posted. And would explain his even heavier than mine weight on the 6 tires.

I talked to Andrew at Mor/Ryde but he told me that they couldn't do it. That was BS on his part. Talking with Gary Wheeler at Mor/ryde a year later to order the axle and he said they could easily do it and would add the third one for me but since I was in RI at the time I opted to have my local garage do the work. Gary had no problem with that but was concerned that I have the alignment correct.

The wheel wells need to be cut for new fender flares and the rear jacks need to be moved back about 2 feet.

As for total cost I can only give a guess since I can't find all the invoices I had for the job.

Two wheels and tires from Trailer Tires and Wheels in Ohio shipped to RI $1360.

Labor to install axle $747

Miscellaneous parts for the install including brake lines, hydraulic hoses and fittings, etc. $588

Axle from Mor/ryde with disc brakes in the neighborhood of $1500, I think less than $2000. No invoice on this. Check with Gary at Mor/Ryde.

The wheel well or fender flares. From DRV. About $160 and almost as much to ship since they are over length at about 8 feet long. I cut the wheel well myself with electric tin snips.

Mounting brackets from Lippert for the rear jacks. I don't remember the cost. The old brackets can probably be reused if they are cut off properly.

If DRV had been willing to install the axle the cost would have been a lot less so they kind of ticked me off on that since they make models with three axles all the time.

That is what I needed thanks!!!

I asume the third axle is mounded directly behind the other two since there is no room to move the front axle ahead.

I don't think the third axle really has much to do with pin weight they are there to carry the load that;s already there.

I will be sure to talk to Gary Wheeler.

IMHO DRV can be a PITA when it comes to some changes and others surprise me they allow.

You assume correctly. To move the axles forward would put them under the door. I wanted the third axle to shorten the length of the frame between the axle and the rear bumper so the cantilever is less and puts less stress on the frame with the lift. The added weight on the axles is due to the lift, the motorcycle and I have frame rails that are twice as thick as normal and a lot heavier. All my main frame rails are 1/4" sidewalls.
