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.

Using BBQ cover as tarp. Expose only the gen exhaust if it is raining.

Note- higher rails on newer trucks than this long box 2003 Chev. No issues with exhaust heat here. Tool box had to go down off the rails or 5er front corners would hit it. Gen is higher so must go forward of hitch to not get snagged under the 5er. (So no tool box with a short bed truck )

I don't think about running it in rain but when I had a Honda a bought a factory cover for it.

I installed a transfer switch in my basement and ran the 10 gauge cord under the overhang and past the pin box. The cable is long enough to put the hood of the truck toward the pin box. On eco we sometimes forget to shut it off.

I have Honda 6500, I built a secure and weathertight box that works great for us. the air intake side is a weatherproof louver and the exaust and hot air are ducted seperatly out the other side. the genset has over 1000 hrs running in the desert and the snow with no issues.

I've run my Yamaha 3000 iSE in the back of my truck, uncovered, from 2011 to 2016. My Champion 4000 watt now sits there in its place after the camshaft seized (I loaned the generator to someone... big mistake.)

Nothing wrong with it being in your truck, although the bed does cause echos of the noise.

Just make sure to secure it with at least two chains or a box as pictured above.

i would say no problem, the ul deal is cause of a safety not in useing it.

while driving.
how often do you drive with the windows open?
long enougth to charge up the house batts from the pu alt?
to power something that requires 110 ac?
most reffers even poor ones will hold cold temps for hrs.
can you bend some sheat metal? just make a cover over the top and comes down about a 1/4 wat. with suport struts. aka: miny shead thing.
as to the exhaust??? send it down through a hole in the bed and outlet at the side of the truck?? up say about half a foot above the cab??.
