Before I ask my question, are they on-topic for this forum? If they are, I'll come back and edit it into this post. If not, can anyone recommend another place? Edit, the next day: Thanks, I'll post my Q below!

OK, ever since I built this house I've been planning an a 8-12KW propane, air cooled unit. I had a manual TS installed when the main panel was installed, so it's ready to wire. I just don't have the cash to lay out for a permanent mount unit and going 2 1/2 days without power in the winter is NOT an experience I wish to repeat. For less than 1/3 rd the total cost of that, I am going to go with a portable gasoline unit and know that I can't run everything. I can deal with that. I'm aware of the disadvantages of gasoline generators but it's the most cost effective. I have an 80G propane tank that feeds my grill and kitchen range but I'm not sure if the regulator on that is the right pressure and propane units aren't cheap. Between the mowers and snowblower, I have a couple 2 gallon gas cans in the garage, so I always have from 1-4 G available. I can easily siphon gas from one of the vehicles if I need more. In fact, I often siphon gas to fill my cans because it's easier than driving to town to go to a gas station. I'll install a drain on the fuel line if it's not there already so I can empty the tank and run it dry between emergencies and maintenance. If the unit I get will let me, I'll weld up a frame and mount it high enough off the floor that I can change oil without moving it. I need 240V for my well pump. I'm figuring at a bare minimum I need 3KW, but I'd prefer to go above that, 6 would be nice. I plan on spending <$1000 on the unit and another 100-200 on receptacles, wire, and plugs. I have run my house on a 5KW in the winter. My questions: Tecumseh powered is out, not taking a chance on parts in the future. That leaves B&S and Honda for engines. With a Honda I believe the GX series is the one I want, I'm not sure which Briggs is preferred (OHV Intek?) Deere has Subaru engines on some models, how are they? Units are out there with both Briggs and Honda engines, but I don't know about the generator itself. Are there any particular manufacturers I should look for, or any to avoid? I'd like to place and leave it in my attached garage for weather protection, and ease of use and wiring. Anyone know a source for a through-the-wall exhaust thimble and flex exhaust piping? I may need a muffler too. The garage is unheated and has a lot of venting, I'd still rather dump the exhaust outside. Some units I'll be looking at more deeply: Deere AC-G4000, 5000 Sears Craftsman (B&S) Model 030251 B&S Model 030430 Sears carries "All Power America" units. Who makes those?

I have a 5.5 kW gasoline generator. It’s an inexpensive Genterac model, but I’ve only needed it for an extended outage once in the last 7 years. I think I paid less than $500 for it. I have it set up to distribute power through the house wiring, but I did it on the cheap. It comes down to a question of how much money do you want tided up in a generator that you may only use a few days every 5 years. My Genterac is hard to start in the cold, so I have to keep starting fluid on-hand. I also use synthetic oil in it so it’s easier to pull through in the cold. I keep 5 gallons of alcohol-free stabilized gas in it’s tank, but have the shutoff valve closed. My generator burns 0.66 gallons per hour at half load (2,750 watts), which is nearly 16 gallons per day. I typically keep 35 gallons on hand, so I can run for about two days. If we get a big ice storm a person might have to drive a long ways to find a gas station that has both power and gas as many more people have generators than have 30 to 40 gallons on hand. Actually, it may be against code to keep that much gas in your garage depending on where you live. That’s why people spend the big bucks for NG or propane systems. My generator is loud and the muffler gets hot enough to melt aluminum, so it’s no easy thing to find some means of extending the exhaust. You need something that can take the heat and is flexible enough to allow for the vibration. Flexible automotive exhaust hoses won’t take that much heat. I wouldn’t recommend running a generator in an attached garage as any leak in the exhaust could be dangerous. I made a 240v cable long enough so that I can set the generator on the driveway and run the cable under the closed garage door to a plug just inside the garage. I also run a steel cable to the generator and padlock it so it doesn’t just disappear. One thing to remember is that if there’s an extended power outage anyone living nearby is either going to show up with an extension cord or might even think you should share your portable generator with them. You can make friends and you can make enemies during an extended power outage particularly in the winter.

OK, research (mostly) completed, it seems I can't do what I want without it costing me an additional $1000 or more. So I'll be getting a portable with wheels. Gasoline, because I don't want to try and store multiple 55 drums of diesel and replace it every year, nor do I want to be bothered with trying to hook up a portable to my big propane tank. I can always retrofit for propane if I change my mind. I already have a manual transfer switch installed, did that when I built the house so I just need to run some #10 from there to a weatherproof Twist-Lok receptacle. I'll have to leave it outside while in use, only problem with that is weather. Too much trouble to try to fit an exhaust pipe thru-wall, plus it would void the warranty. BTW, the "All Power America" brand is all-chinese. Forget that. I'm down to two different B&S units, almost identical, the Craftsman 5600W 0302501 or the B&S 030333. http://www.sears.com/shc/s/p_10153_12605_07132561000P http://www.briggsandstratton.com/engine_power/details.aspx?pid=150 The Craftsman is slightly more powerful (surge rating) and cheaper but not as well built, and the B&S is weatherproofed. But it's a short drive to Sears. I'd have to order the B&S and get it delivered. I was unable to come up with spec sheets for the generator portion, I suspect the B&S is a heavier-duty one. But I did learn that it will cost me $1500 more to get one of the really good ones, no portable units seem to have them. Also, Hondas are way overpriced. I'd step up to a Kohler stationary before I'd pay that much for a portable. I have on the job experience with both Kohler and Cat and can't complain about either. I run datacenters on them, which is probably why it is so difficult for me to step down to one I can afford with my own money.
