I am not sure if I understand your comments or not...
Are you saying while you are still hooked up to the house/garage 15/20AMP receptacle using a RV30-15A Adapter that when you fire up your motorhome installed generator you trip the breaker in the house/garage.
I am also aware that the MH should have an active POWER TRANSFER SWITCH that would separate the trailer 120VAC circuits and the 120VAC shore power cable when the MH generator starts up.
If you are truly backfeeding the house circuits I would expect the house/garage breaker to trip if the MAIN HOUSE/GARAGE circuit breaker is still bringing in commercial power for the house.
You would be feeding the house electrical system with two separate 120VAC sources at the same time. Something has give up????
IMO There is two things wrong with this type situation... The most important reason to always flip the house main circuit breaker when feeding the circuits with an external generator is to protect any electrical workers on the commercial side working on the lines or equipment near your house. They have no idea the line coming from your is ACTIVE being fed by your generator. This is why most house emergency setups all use a POWER TRANSFER SWITCH either manual or automatic when connecting an external generator to the house circuits. The other reason is you may be in big danger of having your external GENERATOR blow up on you. Obviously the commercial power feeding your house is much stronger than your external generator and guess which one will lose the battle...
If I have misread your comments than disregard all of the above....
