72 c10 LWB want to make c20 sort of

[jeep534]

I have a very nice 72 chevy c10 that i want to make a better towing vehicle with. better brakes maybe air suspension maybe full float rear with highway gears. and goosneck hitch in the bed. I want to retain the current ride height is anyone building this sort of thing these days. it has a 350/350 power steering and factory buckets. brakes seem more like car brakes even though I have gone through them.
