Recall all that Dahunter has a Highlander SUV tow vehicle. So, no running the Genny sitting on a tailgate, and weight is a real issue, as are gasoline fumes. Hence the recommendation for a smaller lighter propane generator.

Regardless of the brand a small under 3kw-ish generator won't run both the a/c and micro at the same time (not a big deal, just turn the a/c off for a few minutes while running the micro) but also might not start the a/c on a hot day (a big deal). It's the second or third start in a hot day that taxes the generator the most because the a/c compressor builds up back pressure when it runs and has the highest pressure differential to overcome when it's hot.

So you can always try it without the Easystart and then add it if the Genny labors too much starting the a/c. Just don't do that kind of laboring start too many times, it's not good for either one.

It's not a difficult DIY project to install the Easystart, takes maybe an hour at most. The install instructions are good, the Easystart folks are nice and helpful if you have questions. You can lay a piece of plywood on the roof to spread the load, set the stabilizing jacks, and you don't need to stand up on top to do it. If that doesn't appeal then you dont really need an RV shop to install it, pretty much anyone who can turn a screwdriver and connect a couple of wires up can do it.

Just remember that the lighter weight ones may not have the ability to start the AC reliably. You will definitely need to install a Micro-Air EasyStart on the AC in order to have a chance to get it to work. Also, on the web page, there is a bonding plug. You can build one very easily by purchasing a plug from your local big-box hardware store and connecting the ground and neutral (ground is usually green and is for the U shaped terminal and neutral which is usually a silver colored screw), leaving the brass color screw unconnected.  This is because most generators have a floating neutral. Circuit analyzers consider this a fault. Bonding the ground and neutral will satisfy the circuit analyzer.

 I bought a GENMAX 3200-Watt Inverter Generator.  It is a made in China gen set but a large number of the gen sets are made in China.  It's running output is 2800 watts and so far has been able to run my AC with no easy start and it weighs 47.3 lbs which is why I bought it.  I rarely use a gen set so I figured it was worth taking a chance on and so far no issues.  I can't whole heartedly recommend it because I haven't used it enough.

  We have a Champion generator that weighs about a hundred pounds to heavy for me to lift. The generator has wheels and I use ramps to load generator up into the truck then leave ramps at home. When operating generator I roll it onto the tailgate and point the exhaust out back of truck not to fill the fiberglass cap with exhaust fumes. If I were to buy another generator I would chose a lighter weight generator one that I could lift.
