30lpm will need 20hp plus. If you want a set up like that, buy a skid mount. I got one cheap, was lucky to find it. Similar set up to robs just a different brand. Bolted into the van. Hose reels etc.
You can have a set up that is quick to use by just buying a machine on a trolley as well. Bolt it to the van and get some reels etc.. just have to work out the placement and be smart about it.
