If you have an opportunity to try starting using jumper cables from the house battery to the chassis battery, try that.
Your boost switch might be working fine, but you could easily have a weak connection in the heavy wiring from house batteries to the boost switch, and then on to the chassis battery. Using the jumper cables and seeing it that makes a difference will give you a clue or two where the problem might be.
