It has gone out 3 times since we purchased it used in 2002, and the repairs were EXPENSIVE. So expensive that I have not fixed it this third time it has gone out. I have kept fluids filled and clean and only other part had to replace was a starter motor at
175k miles.

A/C problems on this model BURB were normally the compressor which can be solved by installing the SANDEN compressor, low side pressure switches, and the high side scrader valve port leaks. All of these are fairly simple fixes. I have yet to hear of an evaprorator fail in one of these model trucks, so I don't know what could be costing you taht much to fix.

They never made a 1500HD in the GMT 400 platform. They did make the 1500 diesel which uses all 2500 7800GVWR front suspension and a stiffer rear spring pack, and then there was the 6 lug 2500 which used 7200GVWR front suspension and a stiff rear spring pack. You could swap out your control arms with those from a 6 lug 2500, and then swap out your rear axle to a 9.5" 6 lug version.
