Interesting that you only have one inflation point. So when you go around a corner what stops the bag under pressure from forcing more air into the oposite bag. Airbagman kits have two inflation valves, one for each side, no T piece.
For me it comes down to use and $$. My Gladiator bed use isn’t as a work truck. Most of the time I have Billie Bars for bikes/kayaks and camping gear in the bed so normally sag isn’t an issue due to my standard hauling configuration. 85% of the time sag is due to towing either my camper or my work trailer. A trailer won’t have the side to side potential level loading issues that you would if you were loading things in the bed. If I do have some sag in the bed it’s been when we’ve loaded up bikes which again isn’t a load that shifts. I just don’t have very heavy shiftable loads in the bed. I put larger shiftable loads on a trailer. The other concern was failure points as I do wheel my Jeep offroad and a single fill eliminates potential points of failure. A final point was ease of use..one fill required. We mentioned Chris’s dually in the video…he’s got more expensive bags…brass fittings…higher PSI and load limits with dual inflation points. He also uses it as a serious work truck. If it was a heavier duty truck I’d probably go with a more robust system. I should note that the Airlift kit has the hardware to run dual inflation points should you wish.
