its got a shurflo electric pump, 50gallon tank. only 150ft of hose but the reel looks like it would hold a bigger hose. manual reel though.. however, i need something i could spray with now and then that could be a nurse tank for later. they are asking $850.00 and say it was custom built in 2012. what should I offer or should i pass on this? i just want something small for my half ton truck. will use for filling a permagreen later.
