So my old 35 year old craftsman wet/dry 16 gallon vac finally died, actually it was my mothers because the vac is older then me lol. Which now means it is time to get a new one! The 16 gallon size I had was great, but probably not really needed, but who knows. The vac would be used for the truck/cars for sure, but also cleaning up around household ( not a household vac as the misses needed the best of the best shark vac for that :| ). What size would you guys recommend and even brand?
