Brent,
I have very heavy tool boxes marketed under the name TUFF-BOX for my chronographs. I put a piece of 1" closed cell foam on the bottom, then another with a cut-out for the 35P body so that the chronograph is sitting on and in foam. The Tuff-box is really rugged, comes in black or grey, buy them at a hardware chain-store in town called Canadian Tire, expect that they have them in Walmart also. Cost about 40 bucks Canadian, about half that with real money (U.S.).
I keep my skyscreens in the Tuff-box, assemble them at the range. Tuff-box is easy to tie-down on an ATV, has a good handle on top. It is big enough to put lots of stuff in with the chronograph and screens.
I carry my rods and tripod in a heavy nylon camera tripod case that is sold in most camera shops. It is simply a nylon tube with a zipper that opens up at the top and a bit down the side. Case has shoulder straps, easy to carry or to tie-down. Have two of these since I use two tripods for my setup. They are not expensive, maybe fifteen bucks at a camera shop. You could get a bigger one that both tripods fit into.
I had a machinist buddy make me a pair of 3/4" steel rods that screw into each other to make five feet. He machined flats and shoulders on each end and where the two are threaded so that the skyscreens are located perfectly. Whole setup locks into a pair of Bogan tripods with tilting, adjustable heads.
Also use the original light stands that Oehler sells, they work fine but are a little light. I always carry a pair of small canvas bags or something similar so that I can fill them with anything heavy and hang them on the tripods to keep the wind from blowing them over.
Good luck, we are too **** cold to enjoy shooting these days but the warm weather shouldn't be too far off.
