im new here but I have been reading through this forum ALOT. I am planning to start my business in residential area first before going big. My question is, what is a setup that will work under 3500 lbs. I will be towing with a 2014 4cyl tacoma 2wd and 3500 is the max towing. I plan on getting a cold water pressure washer with 4 gpm/4000psi (honda w/cat pump). What size trailer and water tank would fit me best. This truck is the only option until I can go diesel.
