Title pretty much says it all, but let me try to make things a little more clear.
2008 National Pacifica 40'. Came with the Basement A/C 2 stage unit. It has never kept the coach cold during the 90+ degree temps. Throw in Texas 100+ heat and we would sweet off the pounds with vigor.
Solution was to have a 15K Coleman roof A/C unit mounted in place of the Fantastic Vent. The power cord was run down an interior wall to the basement. From here we have two choice as to where to power it up. While on the road we plug in to the outlet that was intended for the in coach vac system (the in coach vac system does have it's own 115v breaker in the panel box) if desired to use it. However, we have to remember to set the power switch in the rear power selection to 30 amp. Not this does not set the coach power level to 30 amp, it only keeps both stages/compressors from coming on with the basement A/C unit. We were told that the generator may be up to run all three A/C systems, however that the initial power up of the compressors would most likely be too much and trip the generator breakers or worse case burn the system up.
When we are plugged into shore power, I plug the 50 amp cord in, set the switch box to 50 amp to be able to power both basement compressors. I then via an extension cord plug the roof air unit in to the camp ground power 20 amp out let and run all three A/C compressors.
OK, now after all that ground laying work and explanations here is my question. I was looking on Ebay and came across a "RV Hard start up kit"

If I were to install this on the roof unit, do you think that the generator would be able to run, start and cycle all three a/c compressors with out creating a problem.
I would like to say yes, it would work, but then to be honest I have no idea or electrical smarts to back this up in theory. Only positive hopes of it doing so.
