SJMarbu, I am really surprised that California lets you burn anything with all the devastating fires there.
I don't know California geography at all; maybe you are far away from that but so much of the vegetation
there seems to be equivalent to sappy kindling. Good reason to get it out of there, for sure, just surprised they let you burn.
Come to think of it, California must be a great market for chippers....if you can't burn, what are your options?
Now I'm sure you installed earthquake retention rings around those fires. You just never know....
I like your old pumper. 250 or 500 gallon?
We're in the heart of wildfire country here, as evidenced by my difficulties in obtaining homeowner's insurance. A few summers ago the Chips fire burned almost 100,000 acres and lasted until the winter rains came in to put it out. That was just up the Hwy. 70 Feather River Canyon from here, and we had heavy smoke almost every morning for weeks. Almost everybody around here takes fire and burn piles very seriously, and acts accordingly. That fire, though, was probably started by a hiker on the Pacific Crest Trail.
daugen, it's been very dry here, and last year we almost didn't have a burn season. Even then, they closed burn season in the middle of winter, way earlier than usual. This year there was a lot of rain in December and they closed fire season so we can burn now if we like. It all depends on the amount of rain we've received. The only way to economically clear the fuel clutter from forest understory is to burn it. In fact, the USFS is conducting "controlled burns" north and east of Chico along Hwy. 32 this week. It's raining today, a very good thing as we've had none since before Christmas. But back to your point: One of the reasons for the devastating forest fires out here is an almost ban on using fire to clear out the understory. I've talked to old time foresters that used to set hundreds of acres on fire at a time. They knew when and how to do it without burning down the forest, and apparently that's now something of a lost art. As far as earthquakes go, we're far enough away from major faults that I'm comfortable not carrying the earthquake insurance any longer. Last time I checked it was $150/year, down from $900 in the SF Bay Area where I used to live.
I looked at chippers, and still keep an eye out for a good one. But most of the brush here is manzanita and live oak, both very tough woods, and I don't think a PTO powered
chipper would be able to handle it. No way was I going to spend the rest of my life trying to chip the huge piles left from the clearing operations here anyway. And using the chips for mulch isn't the best idea here in wildfire country.
Not sure on the pumper capacity. I know it took a while to fill, and the tank wasn't in the best shape as it leaked continuously. I'm sure welding up the holes is on a ToDo list somewhere

Funny thing about that pumper is it came from a little town called Lithopolis in my old stomping grounds back in Ohio. The neighbor's brother was back there on business, saw the thing, and got my neighbor to fly back and help him drive it home to Yankee Hill. They made it all the way back with only one break down, but since they're both pretty handy, that just added to the adventure.
