Marriage Guidance Tips for Caravanners

My husband is very laid back until something majorly stresses him, like the second time we went caravanning and couldn't get the caravan unhitched. After me chattign happily away with excitement, I do tend to get very excited when off on a trip and me making several helpful suggestions, he lost the plot and threw all his toys out the pram, it was the adrenalin and the stress of it all, successfully it did all come apart (the caravan and not our marriage!)  I broke the ice by runnign past him and slapping his behind when he was tryign to get the first rock peg in, that sorted it! Wondered what marriage guidance tips you have to advise new and experienced caravanners.
