I thought about that as well and did a little research before I put the same type of setup on my wife's Tahoe. It's a non-issue. Ours are rated at 30psi, so not crazy to begin with, and there's 4-5ft of 1/4" OD air line tying them together so there's plenty of restriction fighting any side-to-side flow during cornering. I put them on T'd together like Suke but brought all the parts along to separate them. 500+ miles towing a big asss 8k lb camper around hilly/curvy northern Michigan and zero complaints whatsoever about the setup. If/when I do a setup like this again I'll do it the same way. Besides the ease of filling simultaneously, I also like the peace of mind knowing that if there's a leak or blowout I won't end up with uneven loading and the potentially nasty handling that it could cause.

Before you come back with 6 paragraphs of why I'm wrong and flow calculations through the 1/8" ID air lines, know that I simply don't care. I did my own research, I tested it, and it works great with that setup. Maybe it's different towing 30k lb with a 1 ton dually, but it works with a 1/2 ton towing a camper and I'm confident it'll do just as well with a JK towing a jet boat.
