Agree. I had a factory A/C truck where the compressor and hoses had been removed, and the blend doors didn't work properly. I went ahead and replaced the vacuum lines, and got new parts (Evaporator, orifice tube, compressor, hoses, and a new parallel condenser to work with modern refrigerants. Even still, I was probably out less than $500 in parts, and installation was simple since everything's factory. I already had the vacuum pump and gauges so getting it set up went smoothly. It's ice cold, works like it should, and no worry of fabrication or fitment issues. If it's a non-AC truck then an aftermarket system might make more sense. The new ones seem to keep getting better, and they're definitely less bulky and probably more efficient than the factory setup.
