I plan on carrying my Yamaha 3000iSEB in the bed of my truck. It will be in the front of the bed behind the cab. Is anyone using their generator where they could get wet while running or just driving down the road? If so are you having any problems with them because of it?I planing on having some Diamond plate bent to fit under and behind the generator and then come across the top with some bent down bit on the front and sides a little to give it some protection. It would be mostly open on the front and sides for air circulation and heat.In the past I mostly have had built in generators but with my 5th it is not designed for an on board generator so I have to do it some other way.I know get solar and leave the generator home. I already own the generator so my only expense would be the Diamond plate.Thanks

They aren't UL approved for use in the rain but from what I've read, that is only because the outlet itself is unprotected.

:) Hi, I mount my Yamaha 2400 in the back of my bed, near the tailgate. I have not run it in the rain yet. I made a curved up exhaust extension so my exhaust goes straight up. (before exhaust modification) With my generator mounted in the center, it still made my inside bed panel hit about 200 degrees. I felt that this was too hot.

Years and three rvs ago I had the generator in the back of the truck. I was not as worried about the rain as I was the exhaust. The back pressure may send the exhaust into the cab. I would try and build some sort of extension.

My Honda is at the front of the box with the exhaust on the drivers side. I use a Honda vinyl cover when I'm not using it. I use it mostly in the desert so we haven't seen rain in 3 months. If it did rain hard enough I'd just put something over the electrical plug area to protect it. The exhaust side of the truck bed gets warm but nothing to damage anything.I have a lot of solar but power AC, micro, coffee etc with the generator. I use a ton of power over night so I put the big amps back in with the genny when making coffee etc. Cloudy days need a genny on hand.

I have used my 3500 several times in the back of the truck and it worked well. Be careful with the exhaust as it will burn or melt anything in its way.

Lots of folks seem very worried about exhaust. So Butch50 let me ask this.

Do you plan to run the generator while parked, having your fifth wheel extended over the generator? That sounds dangerous. Maybe with a bumper pull hitched up six feet away? Yup I've done it several times.

If you plan to run the generator while driving, I myself would not (and do not) worry about exhaust. I figure it gets plenty diluted while driving. I run one or two Yamaha generators in the bed depending on circumstances.

Do you have a back window that opens? If you haven't noticed the wind blows forward in the bed while moving. Plumbing the exhaust so that it doesn't come back at you may be an issue!
