I have been involved in the fire service for some time. Yes you could use that type of fire apparatus to convert to an RV but as was stated the suspension on the fire truck is ruff at the best of times (some of the newer ones with air suspension aren't horrible). The National Fire Service will rely on large brush trucks which are more like modified F350 for forest fires. While a pump will be utilized it won't be the bread and butter for them. My point being that the fire truck pumper is radically different from a brush truck.
