Dale,
You'd have to stack to get all that on the tongue of a 13 footer. IMHO, one
propane tank is plenty unless you are out in the boonies for a couple of months.
Tongue
weight measured last year at the Oregon gathering is about 300 lbs. That's with Honda 2000
Generator gas tank full, 20lb
propane tank full and a group 27
battery. You'd be surprised how heavy the tray and box are.
I'm just within my total trailer
weight differential to tongue weight. Whatever that percentage is.
My trailer actually tows better now, than before I put the
generator on the tongue. That would be with or without the anti-sway bar.
