I've got solar as well but here in the south you can't survive without AC!Previous owner installed a new EV6010 in my coach in 2016. Had very few hours when I bought it - and I didn't like it. I removed it, went full solar. I know solar isn't practical for everyone while boondocking (no A/C). Your solution is very interesting - modifying a generator to fit.
I think the 5k will handle it but we'll see. Good alternative if not. I know it will handle them both running.Justin, Maybe an interlock between the A/C units so they both can't start the compressor at the same time will help the cause.
Just a thought.
Slightly louder. 60 vs 56 db for the 5k vs 3.5kJustin, the new Predator is impressively small in your generator bay. How noisy is it compared to your smaller unit? If it's really quiet then I'd guess a lot of people will follow your lead. Quiet power to run two air conditioners at once and extra room in the generator compartment is rather an amazing win win. And if it's quieter than an Onan then it's a third win.
Started a new project on the GMC this weekend.
In my initial build I swapped my Onan for an EV6010 which I have always hated. It's loud and I never could get it to be 100% reliable, it would get hard to start when it got hot outside and would occasionally die on the road.
While building by house I used a Predator 3500w inverter generator and it was amazing. I actually ran it 1000 hrs straight running a dehumidifier and it never missed a beat. Its unfortunately not powerful enough to run both my ACs which is a must for me.
When the Predator 5000 came out I said well that will work! I've been searching for a deal since and finally came across one this week.
Started disassembly and this is where I've gotten so far.
Gutted it down to the essentials, it's TINY.
should save me 150+lbs in the back which should be a nice handling improvement.
Next up is to make a new bottom plate and build some ducting to make it cool correctly without it's enclosure. Luckily the whole thing is well shrouded so ducting should be very simple. I'll likely extend the exhaust out the bottom as well.
Overall shaping up to be a very easy project and I'm super excited to have a generator that I can run when I'm near the coach and without worrying about the neighbors.
Just to stem the tide of people telling me the ev6010 is great and quiet, yeah that's why I bought it originally because everyone said so. Its not. I've heard mine and several others. They run at 3600rpm all the time and have a huge amount of fan noise to keep the radiator cool. I even put a second muffler on it to help (and it did, to a point)
The new inverter gens are so quiet you can stand on top of it and have a conversation without raising your voice. Once it's in the generator bay here I imagine it's going to be almost un noticeable.
Frees up a lot of nice storage space too!
I'll update next week when I get it installed hopefully.
CO detector was removed first thing as it would render it pretty useless un the generator compartment.I have a Predator 3500 , an older one without the CO detector. There is a large following of these generators, people really love them. There's a fb forum dedicated to them.
However, the newer ones do not seem to be made to the same quality level. The CO detector can be bypassed easily, unlike Hondas which is a huge advantage. But there are many owners reporting loss of power production for no good reason.
Also they tend to catch fire or explode sometimes. More than Onans? Idk. There are a lot more Predators out there than onans, and onans have been known to catch fire too. So it's up to you to decide. Maybe the answer is a fire suppression system?
Nice mod nonetheless, keep it up and keep us posted! Very cool!
Got the inverter mounted to the tray
Cut a new control panel utilizing the parts I need only

The engines itself is shrouded with a fan at the front. The intake pulls air over the aluminum inverter on the way into the shroud. I'll likely use some silicone baffles to mostly seal off the inlet to it pulls the air over the inverter but without experimenting I don't know exactly how much sealing is needed there.Love your control panel.
I am also looking to install a 5000 Predator. A few questions if I may.
1). Isn't the outer casing needed to direct the air flow over the fins for cooling?
2). Do you have to modify the gravity flow carburetor to accommodate a fuel pump?
I was watching on you tube
GMC motorhone generator TestFit p3...on KGs Garage. (four yeaes ago)
He did everything that I thought would work but it didn't end well.
Hopefully yours will work fine and I can learn from it. Thanks
Very Cool. I looked at those when they came out last year and almost pulled the trigger (even though I have a freshly rebuilt onan, ready to go into my coach. The inverter power is def the way to go. Will be watching to see your success!
