Suspension control ECU went out - can you swap the bags for coils?

Buddy of mine uses his 4x4 pickups for going to the office so he bought himself a fancy Limited.

It rode nice and smooth - much nicer than say, an SR on 37s - but now his ass end his dragging on the ground because the suspension control ECU is toast. Toyota told him 8-12 weeks to get it replaced.

Questions:
Is this a common problem? (no I didn’t search because I am afraid of seeing @hagrid ‘s posts)

Is there a way to eliminate or bypass the airbag system on the limiteds entirely either by filling them up permanently or replacing with coil springs? Has anyone done this?

I've owned 2 vehicles with air ride; both of them were Lincoln MK VII. This is what I learned:

Do not buy vehicles with air ride unless they are over the road tractors/trailers. You will be unhappy.

 

You rock!

You suck!
