generator for A/C
Do you think a 5000watt generator would run the A/C unit in a 2005 186?

I recommend a Champion 3100 Remote start inverter.... not a contractor generator.

I use a Champion 3100 Inverter Generator (as mentioned previously) for my 2018 Whitehawk 24MBH and it runs my 13,500 BTU AC just fine. It's very quiet, lightweight and has an Eco mode that reduced fuel consumption when full power is not needed.

If it's one of those open framed construction generators, I wouldn't recommend using it to power the trailer since it'll be producing dirty electricity. You can research that further if you want. Will it power that trailer; it sure will and some.
I'd recommend an inverter type generator for the sensitive electronics within the trailer. A lot of folks love their Predator 3500 from HF, or you can get the same one from Northern Tool called PowerHorse. I personnaly went with the Pulsar 4000 watt inverter generator because it was the same price as the Predator, carry handle, remote start, and it was more powerful. A similar model to this is the Westinghouse 4500 or the Cummins Onan 4500... same generators, different colors.
I also love my generator as it checks all the boxes and it provides enough power to my home when storms come through or the random drunk driver takes out a light pole...

Absolutely. Do not buy a open frame contractor style. Too loud. A champion 3500 inverter style is the most popular. It will run the whole rig with proper energy managment. WH fridge on Gas.

I have a pair of Honda 3000 is generators to power with my 266RKS an event trailer I have. They aren’t cheap, but the do run smooth, use very little fuel and are whisper quiet. Each one produced 28 amps... enough to run most any RV and anything else the RV would have.

Whatever you decide on make sure it is quiet. The people camping around you with thank you.

Thanks for the replies guys! I do have a open frame one, bummer. Do you think I can get a decent one for $500?
Looks like the Predator is quieter than the Champion and Pulsar.
I was surprised to watch YouTube videos on them and I really thought they would be quieter than they are really.

Smaller generator
Just recent bought a jayflight slx 7 145rb, and looking to get a generator big enough to run the 8000 btu a/c and the 3 cu ft fridge. Would a 2000w be enough?

Probably not. 2000 watts/115 ac voltage =17 amp output ohms law is wattage/voltage=amp output. Does your trailer have a 30 amp plug... round, larger than usual with 3 prongs that has 2 the same but slanted? If so, it’s a 30 amp plug. You’ll need a 3000 watt generator

If your only option is your 5,000w open frame generator... without knowing exactly which one, they usually are rated at 5kw at total capability. Two of ours actually produce 5kw (total wattage that is divided on two separate circuits) and that really amounts to having half of the generator producing power and the other running along with doing little.
If yours is like our two construction genny's - It will be producing nearly the same as plugging into one of the 120v-20A receptacles at home and running your Trailer. Each side of the generator has just a 20A-25A circuit as that is the rating they put in the circuit breakers.

Cavie, just FYI, I just bought a 2018 145rb...everything I found online said the ac was 8k Btu. But when I popped top and found label, it was 13.5k btu. Needed more power than I thought

Run the fridge on gas. Crazy how efficient it is.

If you have a side wall AC in your 145rb then a 2,000 watt will work ok if you don't try to run the microwave, coffee pot or other big user.
If you have a roof AC you can add a soft start ac system and maybe get a 2200 watt unit to do it, but again, nothing else at that time.

Yes a 5,000 watt generator will easily run a 13,500 BTU A/C as it will draw about 1,560 watts running & about 1,740 watts when starting when not in a soft start mode.
My 13,500 BTU Domectic A/C's draw about 13.5 amps each on 120 V AC current when running.
The very best portable generator, most fuel efficient, cleanest wave power & the quietest is a Honda- it's also the highest priced. As the old saying goes- " you get what you pay for"!!
Happy Trails

Easily...but you could use a smaller inverter generator which would be much better for your electronics than a contractor or construction site generator that doesn’t provide clean/stable power.
