I would suggest staying away from the floor-based systems entirely if you need to haul a bike. I had a similar issue with my detailing gear and ended up going with side-mounted options to keep the main bed floor open for my plywood. Its a much safer bet for a mobile business where you need quick access without moving everything around. You might want to consider these specific items for your Sierra:

• UnderCover SwingCase Truck Bed Toolbox SC100D Driver Side
• These swing out over the tailgate for easy access.
• UnderCover SwingCase Truck Bed Toolbox SC100P Passenger Side
• Using the pair gives you lockable storage for polishers on both sides.
• Dee Zee Special Series Wheel Well Toolbox 37 inch Aluminum
• This is a more permanent, heavy-duty metal option if you dont like the plastic feel. Make sure to double check the mounting points on your 1500 before drilling anything. Be careful not to overload the swing-out boxes since they have weight limits, usually around 75 pounds each. Total cost for a full setup would be roughly $500, leaving you some cash for better tiedowns. Honestly, this is the most cost-effective way to get your chemicals secure while keeping that full bed length for the ladder.

Quick reply while I have a sec. I've tried a few of the top rated setups and honestly they were pretty disappointing for professional mobile work. TL;DR: Most plastic organizers aren't sturdy enough for heavy detailing chemicals. Use a heavy-duty divider and a hard cover instead of swing boxes. I wasted money on the UnderCover SwingCase Truck Bed Storage Box SC203D thinking it would be the perfect fix. Unfortunately, the mounting bracket is a major weak point. When you load it up with heavy gallons of soap and degreaser, it sags and rattles like crazy on Texas highways. Not exactly what I want when I have expensive polishers inside that box. Its just too flimsy for the price and the security is laughable if someone really wants your tools. I also tried the BAK Industries BAKBox 2 Fold-Away Utility Box. It is supposed to be heavy duty since it integrates with the tonneau rails, but the build quality just isnt there. I had issues with the panels bowing under relatively light loads and the folding hinges felt like they were gonna snap. Plus, it sits right at the bulkhead, so it still interferes with my bikes front tire when I am trying to load up. If you are worried about security in Dallas, stay away from the plastic stuff. I would look for a heavy-duty Heininger 4016 Hitchmate Cargo Stabilizer Bar to keep your chemicals upright and then spend the rest of your budget on a solid locking tonneau. Most of these storage solutions feel like toys compared to actual work gear... just my two cents.

@Reply #2 - good point! I had issues with gear sliding and breaking expensive bottles. Unfortunately, cheap bins won't work.
