Hmmm...that sounds like a pretty good way to do it.I use one hand on the top handle and one on the bottom of the cab when I have to heave it up to any height.
S-prince, there's a possibility recessed side handles could take up more room in the cab, but if they do, it won't be by much, and I doubt it'll change the sound of the cab. I wouldn't install them just because it would require cutting massive holes in each side, but I don't see it changing the sound...unless of course you don't seal the holes all the way and it has an air leak.
