I am in the process of building a new spray unit. The old one i have out grown so this winter i got the plans put together for a new setup. This is how far i have gotten in one day. Should have it completed later this week. Its going to be a two 110 gallon tank sprayer with electric hose reel. Also will be able to lift the unit in the back of the truck with the forklift. That is what the forklift pockets are for on top. I use the shop at my dad's work sometimes for the larger project. I would says its a 40x80 with two bifold doors. Also has a heated floors which is great in the winter time.
