I love the roadster doors on the M715. Lots more air in the summer and great visibility on the trails. However, as pointed out above. Stuff does tend to land on my left thigh. I got stuck behind a garbage truck on I-410 around San Antonio a few years ago. Some kind of really nasty smelling liquid was leaking out. I had to smell that smell for the rest of the weekend since we were on our way out into the hills for camping and wheeling.
Your state will vary, but if Jeeps are legal with no doors, you probably are too. However, I tried running my M715 without doors first. I was having to hold my leg in all the time. The 1/2 doors keep my foot in, let my leg rest against something and make a great raised foot step for highway cruising.
I made mine so the mirror was still there and the outside door handle was still there. That doesn't leave that much room to enter and exit from. It is a BIG step up. Getting down is great through the gap though.
Basically, figure out if you want air flow, trail visibility, entry/exit ease or whatever as your main goal and make what fits that goal work.
Oh, Jeff and Joe. Thanks for thinking of my truck when this came up.
