AC power questions

Hi,
I just bought a TT (Riverside Retro 177) which Iím pulling with a Toyota, FJ. The salesman said a 2000 watt Yamaha inverter would run the a/c, even in az in the summer. Wrong- Itís not even hot yet and the a/c unit keep kicking off. I am planning on getting another one to run in parallel (seems easier and quieter than getting a big unit to lug around)
Question 1) is this the best way?

Second, Iím using my TT at peopleís homes like an office, so wait time for cooling not ideal.(esp when itís 115) My FJ is not a pick up so could I run the generators while driving if I put up some sore of barrier to keep the exhaust going out the back. (plastic liner or hose? ) or is there some other way. There is a 110 Volt outlet in the back but only draw 100-400 watts. (any way to use this feature?)

Thanks in advances for helping a NEWBIE.

Welcome!

Your Yamaha generator is likely right on the edge of being able to run the air conditioner compressor start surge. That said, be sure all else with heavy draw is turned off or switched to gas, such as the water heater and refrigerator. And yes two units in parallel is popular due to being easier to handle, and when not running air conditioning only one is needed.

Installing these generators inside the tow vehicle is something I would not recommend, due to the issue of the fumes. Maybe a rack added to the rear of the trailer to hold the generators would be a better solution.

Yea, the issue is the a/c run through on/off cycles and doesn't have the juice to restart. just wait till summer.

Ok, so no generator in the truck. I will have to look for a economical way to add a rack. But two generators should work, right? It seems like I'd get more quieter power for less money getting a second 2000 vs getting one bigger unit, or am I mistaken?

thanks

I could run the roof air on my last 5er with my 2000w Honda inverter.
BUT , while doing so the Honda had to be at max RPM, not on auto idle, and nothing else could be on, even if the batteries were down and the converter/charger was working hard , that would cause an over load.

Yes, two such generators designed to be paralleled would provide for the air con use and is usually a better watt / dollar deal, provides lighter units to handle, and allows the usage of just one if the air con is not needed.

Your A/C may not have a start capacitor or it may be too small...have a look at this link for information on the problem.

well, I order the second one already, But this was an interesting article. I will need to see what capacitor mine has. It may be changing.

You need a 3K generator to run A/C. Running two 2K units in parallel is a good way to do it. When A/C is not needed, you can run just one unit. I would suggest a rack on the back or if you have the ability to add some tongue weight, they make a rack for over your propane tanks. Either way, you can leave the generators running and cool the TT while driving. Keep in mind, the roof A/C may not be as efficient while driving because of how the wind blows across it. Not a huge issue, but you could lose a couple of degrees.

I'm going to get the ignorance flowing here. How do I find out how much tongue weight I can handle? I could see a cargo carrier like this one working. The gens weigh 44 lbs, so only 88 for generators + a gallon of gas each (about 14 more) + the weight of the carrier (? shipping wt is 68) so about 170.
