Options for extra weight carrying capability

much better than those sumo.....maybe but much $$$ too and need a compressor each time you want to inflate them.

Sumo do the job pretty well, install is 30min, ride like near stock when unload, no air leak.

 

I didn't find the cost differential inhibiting..
I suppose I still like the airbags over the Sumos. Like I mentioned, I've had both.
They both have their pros and cons.
FOR ME, I prefer the Sumos as they do what I need, and they are maintenance free.
But I did like the adjustability and the airbags. As "near flawless " as my Firestones were, they were not flawless. But I do endorse both.
I'm retired. Have a lifetime of tinkering with my FJ40, (47 years of tinkering, lol).
Set and forget becomes attractive.
