Does anybody know of a good one? I have a rack on the back of my camper and carry two 2000 watt Honda generator married together and a 3000 watt Honda generator. This works pretty well because I use the power feed line off of the 3000 into one side of the 50 amp and the feed line off of the two smaller Honda generators into the the other side of the RV 50 amp plug. In other words one side of the fuse panel is feed by one side of the 50 amp plug and the other side of the 50 amp plug feeds the other side of the fuse panel. I can run both ac's but have to be real carefull of the rest of the power useage.
Sorry, got carried away. My question is the three generators running at half to full throttle on the back of the 5er makes a lot of vibration inside of the 5er. Is there a good vibration mat that the generators can sit on? It can be annoying especially if running them when your trying to sleep.
To help with the question, I suspect the answer is less likely a damping mat, but more likely a damping foundation. Something like a platform that mounts to the frame via grommets / springs in order to allow the platform to vibrate all it wants without translating this noise to the 5-er's frame.
Reason for going the platform route is that I have seen diesel applications where they were hard mounted to the structure yet absolutely undetectable by feel or sound even when just 3 feet away. Panda marine generators comes to mind.
Another possibility is damping material on the frame to prevent the harmonic from setting-in. This might prove more work as it will take some trial and error to find the right spot(s) and correct type / amount of damping material to absorb the correct frequency. If the trailer's frame is easily accessible, am suspecting that a crude way of finding the optimal spot for damping material is to feel by hand and might get lucky by feeling a slight 'buzz' in one (or more) spot(s) that matches the generator's frequency. Or, use a directional sound device to hear if there are locations on the frame that are louder than others.
Water makes a good isolator. Maybe a water bed....
Ha, I used to make a lot of vibration on a water bed in college! What about the wave action, might turn into a tsunami lol. In all seriousness Nate, if it was thin enough but yet support the generators so they don't bottom out that's a great idea.
Adam, they are not mounted to the luggage rack but Honda does have a rubber foot on each corner of the generator. They just don't do enough to help but it would be terrible without them. The mount to camper is double reinforced to help stop sagging with the weight. I'll try to get a picture later.
The hitch goes across the back tieing into the frame on both sides. The receiver hitch is in the middle with support bars, one under the hitch and one over the hitch on both sides. It kept sagging down until I added the support bar on top of the hitch. Now its real strong and doesn't sag down. I can't even shake it but I get a lot of vibration.
The upper support beams look like they are touching the RV's shell. If this is correct, might try a quick hack of cutting a couple sections of garden hose and wedging them between beams and shell to see if this does anything to dampen the resonance.
