Onan LP 5500. Need a tanker of propane??

[06bowtie_guy]

Just bought a new trailer, I added the propane 5500 watt onan genny for those days where i might want to cool down yet there is no power plug ins. Trailer has 2 propane tanks and no fuel tank so that is why I went that way.

Searching I have found people say bring lots of propane. I was wondering if anyone with a similar generator could shed some light on their actual usage while running A/C.

Wondering if I should buy a couple of 100 lbs tanks or would the 2 30 lbs tanks last a weekend? A/C might be on for 6 to 10 hours in a day if it's hot and the little guy is with me.

Trailer should be ready for pickup later in the week with a planned outing right away where I will be without hydro so going to run the generator/ break it in.

Thanks

My experience with our 6200w Onan l.p. genny
Is about 1 gal per hour running the a/C, that's about 6 hours per 30# tank,
you might get better fuel economy, with your new Onan
ours is 19 yrs old and has over 3000 hrs on it

We have large frame mounted tank, in our DP, approx 28 gal, that about 130#

For a/C use, I think you would be better served with a gasoline version
Easier to get, easier to transport, available every where, more energy per gallon
