Hi John,
Assembled/Dis: Depends on the distance to the match. As I live all of 10 miles from out club range I usually break it down into front ammo box (this is heavy on mine cause I've got enough ammo to start a war), the bucket, top box and the top box hangy thing (tech term). Then just man handle the rest into my truck. I've got bolts and wing nuts that hold the rifle rack part on the base part. I went with the smaller wagon at Wal-Mark as I knew I would have to lift this. Takes about 5 minutes to get it unloaded, assembled and loaded up with the guns, water jug and stuff.
trans guns:
long: went to Academy and got a couple of their double rifle cases, abut $25. They do nicely and will fit inside of truck. Not looking for old west here, just safety
revolvers, holsters, etc: Wal-Mart in tools has a canvas tool bag, zipper on top and double handles. Tan in color. I carefully cut the logo off (razor blade) and does a nice job of looking "sorta" like a carpet bag. Midway has real carpet bags for $40 or so. Wally World's was $16 each (got two of them)
Vehicle: Dodge Datoka 4 door pick-up. Had their earlier version 11 years ago and finally wore it out. New one now offers 4 doors--makes it nice to store stuff inside. Do have the problem of what's in the bed getting rained on but we can fit everything but the wagon and rifle rack inside.
Let me know if you need any more info.
