That's the best wash- when someone else is doing it.
This is going to sound a little personal, but how big of a guy are you?
I'm 6'6" and I'm not fat, but I'm not "slender" either, and I have a hard time getting in and out of the cab on our national. Its like the door is too far ahead, and into the control station- ours has levers (simple is better you know) and I end up getting hung up on the levers getting in and out of the cab. My old groves are okay, and the rt is fine, the 70 ton is huge inside, but its a 10' wide carrier.
I was wondering how your cab was on the new manitex, the pilot controls would help a lot for room in the cab, but I was wondering about the rest. It looks like yours has the smaller cab than the 40 and 50 ton's do. I ran a altec a little bit, and it was really crowded, and had a front opening door, rather than a side door, it was like falling into a skid steer. It tended to cook you a little because it didn't have much cross flow windows either.
Most of the truck cranes, the door doesn't go to the front of the cab, giving room for the controls and the dash, and it not interfering with getting in and out of the door.
