There is ample room for storing chemicals and accessories. You will also see to the right, a separate chemical lock box for pest control chemicals. Installed into this truck is also a sink for filling chemicals and washing hands after dealing with chemicals.
The sink (that is in the middle of the photo, when not in use, has the arm of the tap fold back and the back plate folds shut so the area can than be used as a work bench. Note also just to the bottom left, a 15 KVA generator has been installed that can run external lights or other electrical equipment. At either end of the top chemical shelf you will see toggle switches that control both of the on board demand pumps.
