Mohawk System 1 install location

[kenners]

I have recently purchased a Mohawk System 1 and am running tape measures around the bay it will be located.

Vehicles will include:
2008 F350 Crew Cab/Diesel
2005 Volvo XC90
2010 Volkswagen Jetta
2007 Toyota Corolla
1989 Porsche Speedster

The longest wheelbase is the F350, so I'm trying to figure out axial placement in the bay so vehicle can be lifted with the door closed.

I have right at 30' from door to wall. I will have a 32" work bench on front wall and leaving around 2' between bench and truck front bumper and then around 1' between rear bumper and door.

Another twist is that every 10' from the door is a roof truss that is 10' 9" from the floor. It appears that the truck cab will be able to fit between the trusses as there is no ceiling other than the tin roof.

The owners binder gives information on placement from one column to another and shimming for alignment, but I presently don't see any advice on axial placement within the bay other than suggested 12' 8" for full size cars and 11' 8" for all others for centerline of column to front wall.

Looking for real life information on how far from centerline of column to door on anybody that has lifted long wheelbase 4 door trucks. Also any information on centerline of column to front wall or bench.

I have read where one person installed columns I think wider than suggested to allow use on smaller vehicles, ie a porsche to allow legs to get between wheels. I have also read where going wider than suggested would cause more stress on lift/mounting method while lifting heavy loads.

Any and all information is greatly appreciated as I hope to start drilling mounting holes soon.

Thank You
Ken

No help here, but I'll be watching for answers as I just bought a used Mohawk, so this will be interesting.

In the shop I work at we have only an inch or so between the back of an F-350 crew cab and the door and that works fine.
Make sure you measure with the trailer hitch ball mount installed if you have one.
On an F-350 with a diesel you might want to have the truck a bit further back from center on the hoist to compensate for the heavy engine so take that into consideration too.
We made the mounting plates on our big Mohawk larger because the floor was starting to crack around them. If you moved the posts out further it would add even more stress so I wouldn't do that. Just make sure they are wide enough apart to clear the truck mirrors easily.

I was wanting to keep the 1' to the door to allow if I left the stinger on the receiver.

I was also thinking on sticking with the recommended 10' spacing between columns. The truck with mirrors out will clear 10' and they also power swing in.
I was pondering the idea of setting columns in place without the arms (free standing/unbolted) and driving vehicles into location and seeing how each vehicle fits with arms. Is this process not recommended ? Or I could bolt down the pump column then drive vehicles into bay. If I go this route and deviate from the 10' spacing it would put the lift offset to the right of door opening.
I could also NOT put the work bench on front wall, leaving more room in that direction, but that would put the windshield or cab right at the 20' roof truss. What can go wrong probably will at some time, so am wanting to keep Murphy at bay.

Anybody have a dimension from the centerline of the column to the back end of an F350 Crew Cab long box with a diesel ?

How did this turn out? I have 30 foot to work with as well
