Survey on new technology for truck campers

Need quiet fans not let the whole camp know what your business is when they sound like a C-130 taking off. Need better insulation so your not camping in crowded summers. need 3 way water pump switch with one in the bathroom. Aluminum escape hatch lids/ covers so they last. Last, they need to slightly reduce the voltage to the furnace fan since they rumble too loud and a macerator pump out not dump out with a hard to clean hole cracking corrugated sewer hose.
