Those of y'all that are walking around with your noses in the air, thinking you're better than your neighbors, may want to use an umbrella when it rains. Helps to prevent drowning, you know.
I use a Big Buddy, found that the small tanks left something to be desired so now I run a large tank and a "green" hose to feed the thing. It does the job, and considering that this van is a '98 with 427,000 miles on it the less permanently-mounted stuff I have on it the better. Maybe the next van can be outfitted with an Espar, but for now the Big Buddy will hold its own.
OVM, I seem to remember reading about that incident where the hose pulled apart. Preventable if I remember right, these things do demand a certain amount of attention to be taken with them. Not allowing freight to fall on a connected hose, or anything else that can forcibly break the connection--- that hose didn't just fall apart as I remember the story.
Special note: Before I roll, I've shut off fuel at the tank and then allowed the burners to run off the remaining fuel in the line, that allows that the line will not be pressurized while the van is in motion. It's in the instructions, just so's everyone who uses these devices knows.
Special special note: The costs of an Espar don't end with purchase and installation, it gets the fuel it uses from somewhere. I can assure you that elves don't bring Espar fuel in reindeer-drawn tankers for it. That device gets its fuel from your main fuel tank--- so you HAVE TO count the fuel it uses-- not as much as running the engine, but still not non-existent-- into the overall cost of operation. Better figure on maintenance too. It might not be much, but it still exists. Bad luck on you if the line from the tank to the Espar gets a leak, or the heat exchanger gets cracked slightly. That CO detector is cheap insurance regardless of what kind of fuel-using devices we use to heat our vans, just sayin'.
