If you want one for the back of a ranger, check out PK sprayers. 5 GPM rate of flow as opposed to the 2.1 fimco. They have a bunch of different options you can choose from. I would also go boomless if you can. The ten foot booms are nice, but only cover 10 ft. A boomless sprayer that has 1 -3 nozzles will cover up to 30ft at a time. There are a ton of different options out there, but I would recommend boomless with a higher GPM pump. PK has 25, 40, and 60 gallon tanks. Good luck
