I think we are all in sore need of alternative MAXTRAX, et.al. mounting methods. I've found I use MAXTRAX one of two ways - if I'm Overlanding or hitting fire roads, I just throw them on top of my Gobi and use short ratcheting straps. Cheap and easy. However, there have been times I'm off-roading (most recently at Windrock, TN) and I'm using them the whole time. (Here is a vid of using them to try to avoid hitting an active natural gas line - )
However, it took too long to keep dismounting them, and then re-stapping them to the roof. If I just threw them up there, they would slide around and be annoying. I ended up having to keep opening and closing the lift gate to throw them in there, which got everything muddy.
So I started looking around - looks like Blue Ridge has a tire-mount MAXTRAX bag (which doesn't get reviewed very well) and MT has their tire kit. Neither of which help me - so I'm kicking ideas around. I am thinking about buying the MAXTRAX tire mount with the two hooks. Then figuring out a way to mount the hooks to the Gobi Ladder. That way, for long trips I can store them there and sinch them down. If I need them frequently, its just a matter of un hooking them.
Bottom line - there is a large market for cheap, easy to use recovery mat mounting options so people don't have to keep building their own.
