hey tileman: thx for the great info! that's a cool website you have. i figured somebody else must have thought of this & tried it. you've saved me lots of r & d.
highbeam: if it had been some secluded wilderness area i wouldn't have done it, but it was a sera enduro. just about everybody runs a generator in the warm (or hot) weather, the campground sounds like a tank division is running maneuvers all nite long. (ever camped in louisiana or miss. in summer?) i used my generator, which normally runs the a/c in my camper when needed, to run my fan & a buddy's fan in his enclosed trailer, along with his lights, etc. i almost never use the shower, or the water tank, or any of the camper stuff besides the stove, toilet & beds. i really use it only for 1 nite at a time, at enduros or organized trail rides, so long stays in it or security won't really be an issue. the only real advantage the camper has is that i don't have to put it up/take it down in bad weather or worry about trying to sleep in it in a storm (i admit, this has happened to me with a tent, & it's a drawback). but i also don't have to haul it back & forth or work on it all the time or pay to store it; i'm trying to decide which set of problems/benefits i'd rather compromise for, & the tent has some attractions. my buddy & i have used the gen. to run a window unit in his enclosed trailer, w/an extension cord, w/no problems, & i know that the new lightweight rv's w/ the canvas ends have a/c, so that got me to thinking about trying it in a tent.
nik, i figure the tent won't hold the cold air for long, but the tent is so small & i'll be so close to the unit that i think it'll work fine. my big worries were the kind of electrical engineering/safety problems that tileman has been working on.
thanks, everyone, i'll keep working on it.
