Soft start capacitors
Should every ac have a soft star cap installed? If so, why don’t they come that way? Is there any downside? Thanks

by my understanding...
soft start means some form of software is controlling the current limiting. microair for example, is a soft start controller
hard start means plain old physics is controlling the current limiting. SUPCO spp6 for example
why don't all ac units have one installed? cost and need. Most RVs that spend their entire life sitting at a seasonal or full time site, wired into the grid, don't need any help starting and restarting the motor. so the hard start cap would be one more thing that can wear out and need service, and it's not providing much benefit.
for soft starters, they're very expensive and again, mostly redundant.
why trailer manuf haven't switched over to inverter type split unit AC, with a digital compressor motor and separate fan motors, who knows ... these mini split roll off assembly lines by the millions and have decades of industry experience behind them now.
the old fashioned Coleman (assorted brands) rooftop units really seem dated, but maybe Elkhart has an enormous warehouse full of the Coleman, so they keep using them and keep building more?
