The LM Milk crate isn't anything special it's just a regular milk crate except rectangular instead of square. I added some bungee. I had an issue with those yellow topped crates where I closed one up after I thought everything was perfectly dry. I opened it a month later and everything was covered in mold. Apparently something was just wet enough eventhough I left it open for 3 days to dry. The LM ensures everything is dry.
As for bags, I went and looked and took a photo. I got a cheap Scubamax one that my wife and I share for bailout regs. It still has plenty of room for more regs. I don't currently have stage or deco regs in there. My wife uses the Halcyon bag the most for her sm stuff. She has a sm set and a stage reg in it with tons of extra room. I use the old Poseidon one for sm, and it has 5 regs in it (looks like 4 in the photo, but one's hidden) and it's pretty full. Our BM stuff is in storage bins in the house since we don't use them often anymore. We also have a no name black reg bag we use for travelling that will hold 8 regs in it. It gets heavy as hell. All the bags look different, so we know what's in what bag. I've never grabbed the wrong bag for a dive weekend yet, though I triple check.
We drove the 3 hours to cave country regularly with the regs on everything. It was perfectly fine for doubles, but I had an spg on 2 separate occassions get dinged enough to leak on stages. I'm also packing for 2 people, so things are a lot tighter in the car. I eventually gave up on leaving stuff rigged except deco bottle.
