Generator Recommendations

My husband and I have a 2018 3731FL. We have not had an occasion to boondock yet, but would like to do this in the future. What brand and model of (external) generators do you recommend? We do most of our camping in GA & SC. Itís HOT down here, so we would want to be able to run both A/Cs and it would need to have a 50 A outlet if at all possible.

Tracy and Tammy,

The gennys with 50 amp plugs tend to be big and heavy. You may do better with a smaller setup that is easier to manage but will run only a single a/c. You will find several threads here on different genny options with plenty of opinions. If you consider modifying your a/c with soft start kits you can get by with smaller gennys. Start using your a/c early in the day before it gets hot and you may do better than you think on a single a/c. If you are hard over on getting a big genny - two options to consider: 1. Add an internal 5500 watt or 2. Mount a big one in the back of your truck.

I use a pair of Honda 2000s plus solar and an inverter for our boondocking. The only time I start the gennys are when I need an a/c or cloudy days when I need to recharge my battery bank.

You will need at least 5000 watts to run both ACs at the same time. Honda makes a 6500 watt generator for about $1850. It will be noisy but it’s a Honda. Harbor freight makes a 3500 Watt Preditor generator for about $750. You can run them together. They are quiet they look good but they are Harbor freight so quality may not be as good as the Honda. I saw one running for saveral hours. I was impressed. You might wont to go to the Harbor freight store and check them out. If something happens to my Honda IS 3000 I would buy one.

We've used two Honda's we bought used 8 years ago and they're still running good. As stated above you'll either need soft start kits on your AC's or set one at 60 degrees and once it's running turn on the other and don't use any other electricity if you go with what we do.

I’ve been looking at the WESTINGHOUSE 2500 - quiet, light - could do the trick

Tracey if your primary objective is to run both of your AC units I would recommend going with two 2000 watt inverter generators of your brand choice (Honda, Yamaha, etc..). These brands can be run in parallel with an accessory parallel kit. In addition to keep your AC starting current low there are products that are basically starting capacitors that will significantly reduce your AC starting current allowing you to run other electrical equipment while starting the AC unit(s). Micro Air Easy Start is one of these products that I can speak to as I have them installed. I have no further affiliation with product. This setup will allow you to purchase two smaller, less expensive generators. The inverter generator will also provide you with pure sine wave (cleaner power) output suitable for use with sensitive electronics... if that's needed. The two smaller gen sets are much easier to handle, stow and move than a single larger generator. Finally assuming the AC units are the main objective in your generator decision you don't need that large of a generator if you use an Easy Start on each AC unit.

You do not need 5000+ watts to accomplish the above. If you want that fine but don't be mislead to thinking you require it.

We camped throughout the Southeast (Bristol, TN, Darlington, SC) in our 2010 3400RL and found we could get by with the front AC at night and the rear one during the day. With a soft start, neither AC presented a problem for our Honda e3000is. It's not inexpensive and not terribly light but we managed for several years. Eventually my lower back (and my doctor) told me to stop lifting heavy things (in excess of 100lbs) so I installed an Onan 7KW. It is terribly convenient.

Gave up some storage space but we no longer have to turn the AC off to make a pot of coffee in the morning.

I have a 5500 watt and 7000 watt Generac generators. These are running watts, not starting watts. I installed a 50 amp rv plug on each and plugged them into my rv and they both ran both a/c's together and micro-wave. I do not have any type of easy start on my a/c's. If you are planning on running any thing you want as if you were on shore power then i would think you need no less than 5,000 running watt generator.If you are running only the a/c's then you could go 2-2000 watt honda's or equivalent. Just remember if you go just about anything less than a Honda you will have a large noise factor. I wouldn't want anyone within 200 feet of me if they had my Generac's as they are contractor generators and very noisy. Mine are only for emergency at home such as a hurricane.

I'd get a 30KW Multiguip on a trailer. Put a hitch behind your 5th wheel & tow it to camp sites. That way you would have more than enough power plus if your neighbors need power you would have for them to!

Just be careful what EMS you use. I installed soft starts on both AC units and I intend to power them with two Honda 2200EU's running in parallel. I'm having a problem with my Surge Guard EMS throwing an 'Open Ground fault error' when I try to run just one to power on AC. Based on feedback and a Youtube video, I made a plug where I jumped between the ground and the neutral and plugged it into my open port on my generator but still go the same error. Still not sure how to get around this.
