Coleman-Mach 48008-966 AC large voltage drop
Back in October I got a new Coleman-Mach 48008-9660 3 P. S. heat pump and a 9630-715 non-ducted ceiling assembly. With warmer weather, I've noticed a problem with the air conditioning. On LOW COOL...

This is likely your issue (might be compounded by marginal park voltage which will result in higher amperage draws and amps are what triggers the breakers to trip.).
Newer electronic thermostats have a delay built in, once the compressor shuts off, it won't allow it to start again for a few minutes. This allows the pressure to drop allowing the compressor to start more easily.
"Anti short-cycle" timers are also commonly sold for retrofitting A/C units that weren't originally equipped with this feature - Example here.
I doubt this would work on a RV Mechanical tstat controlled system. The link refers to a 1.5 amp MAX current thru. The RV AC mechanical control tstat will be susceptible to the current load that the compressor pulls(up to 18 amps short milliamp load). The link shows a system that would be on the smaller(16 to 22 gauge) wires of a wall thermostat(24 volt) like in a house. RV wall tstat have a upper control board that is where the time delay is. The time delay is not on the wall tstat. Doug
