SLO Camper
Junior Ranger
Well, we are a few hours out of sync. I found that if the mounting plate on the ARC jack is removed it is a direct replacement on the existing mounting plate from Campinn. The Campinn jack can be removed by the snap ring, the ARC jack, sans the mounting plate, can be slipped on and the snap ring replaced. The coupler height rises to a max of 19” with a front to back slope of 2”. There may be a difference between the model I used and the model you used. The non-rachet model weighs 25 lbs.
For anyone thinking of trying this upgrade, I can confirm that the ARK 350 will fit without having to change the mounting hardware. Merely, remove the snap ring and swap them out. Easy peasy. It is a very nice upgrade as the ARK is MUCH more heavy-duty and it has dual wheels for reduced resistance.
