I have the 55 gallon boom model. I bought it at agri supply allready put together. the first time I started the pump, fluid came shooting out where the gauge screws into the main valve. they screwed it in too tight and cracked the fitting. went to the local tractor place, and they had nothing that would work. so we pulled the gauge out, wrapped the cracked piece with electrical tape, and put a piece of hose over it and held it on with a hose clamp, and screwed the gauge back in, and no more leak. I called agri supply, and they said they will give me a new part. after spraying 2 acres the straps came loose, 1 actually fell off, but the tank stayed put due the bolt placement. replacing those with ratchet straps. I really like the handgun on it, it is like a pressure washer want, really heavy built. can spray, and the flush it out, and add a cleaner, and wash the tractor with it, it works really well. the boom sprayed really nicely. the mount is plenty strong, does not need to be any stronger. hopefully 2 acres will be dead this weekend.
