I've wondered about this. I think if we were staying in North America that we wouldn't hesitate to try an air bag system. I really like the idea of it. And for what it's worth, the furthest we've gone overlanding so far in our lives is to Puebla, Mexico South of Mexico City, and to the tip of the Baja Peninsula. But with our plans to drive around the world, we're really hesitant to put any systems on the rig that could potentially fail or make repairs more intricate. I'll ping my friend @Dan Grec and see what his thoughts are on your suggestion. Dan has really been instrumental in helping us make wise decisions for our build as a result of his fairly extensive experience in many of the areas we plan to travel. So please don't take it as an affront. Because I really appreciate the suggestion and would love to have it in our rig. I just want to make sure that I'm not potentially creating a problem I can't fix when I'm miles and maybe countries away from a reliable shop that understands such a system. ~ Eric
I personally avoided air bags on my Africa JK for exactly the reasons you're thinking.
Then I met a German couple who's been hardcore 4x4ing the world since the 80s, and they ran air bags in their 80s series LC they toured TONS of north africa in. He said it was a great solution, and only after about 8 years did they start showing signs of wear and might need replacement.
He also had airbags in the E350 he was driving around Africa, they never gave any trouble and were great.
I have no personal experience, but I think "helper" airbags could be a good thing given you know you'll be flirting with (or over) GVWR.
If I were planning another mega-expedition (multi-country, multi-year), in a "house on wheels" build, I'd absolutely consider them.
