I have a Coleman Mach 9.2, and it works great if you have some shade. If you are out in direct sunlight it will have to work hard to keep it comfortable. The Honda 2000i handles it nicely.
I have the same camper and AC,
First about the camper load. I think I run up to 3500lbs loaded.
On my 2006 3500 Dodge 2wd SRW I was just below the tire capacity on teh rear (3200 lbs). I also tow a 7x14 trailer with water in the front (extra water for camper). I was rigth at the safety numbers on truck. I was due for a new truck so I bougth a dually. personal preference.
On both old and new trucks I added a "big wig" rear sway bar, this sway bar is a whole lot bigger than a stock sway bar if your truck even had one stock (neither of my truck has a rear one stock).
A sway bar is a big chunk of steel that is a torsion bar type spring. It is attached to the rear axle AND the frame on both sides.
In order for the body to sway from side to side, it has to TWIST this bar. When you start to role the body, the body is pushing down the sway bar on one side, than the sway bar transfers that load and also pushing down on the opposite spring as well as a little twisting. This shares the moving weight to the other wheel.
I hear others talk about more springs for sway control? I disagree, All the other devices do is add more spring to each side, they do nothing to transfer or share the load from one side to the other as the body tries to role on the suspension.
Yes this "extra spring" can make it feel like the sway is less, but the G forces of a "sway movement" is still being applying X lbs to that one side, and its not getting shared to other side through sway bar.
Plus the sway bar is one of the cheaper modifications.
Mach 9.2AC:
we have sat in open ground at Outer Banks of NC (beach) in direct sun, 98 deg, very high humidify, Mach 9.2 never had to come off low fan. same location in our past 5ers we suffered with AC's that only dripped the temps 15 deg from outside temps. This AC in the WC you can set it to 70 deg if you want and it will still cycle even on low fan at 98 deg outside full sun. Yes the bathroom gets warm with that big skylight but coach still stays cool.
I seem to recall reading that the 9.2 makes the same amount of cooling on both high and low fan, but low fan is quieter inside.
somewhere I read that the 11.? actually draws less power than the 9.2?
This AC is little louder outside than a normal camper AC because of the low profile and they use a bigger fan to move air across the outside coils.
inside its a little louder than a ducted AC because the fan is right there as apposed to blowing into a duct which acts like a big muffler.
in the WC with the Mach AC, the AC has a thermostat on the roof controls. When temp setting is meet the compressor motor shuts off but the fan continues to blow.
I (and several others here) have switch to a thermostat on the wall that cuts the AC power to the AC when temps are meet, thus both the compressor AND the fan shut off.
When running Air conditioner on Generator, first I switch my outlets over to DC invertor (this is so my Satellite receiver don't reboot every time AC starts), I turn off AC charger breaker (I charge with solar also), and make sure refreg and hot water are on gas. Than i can run the generator on ECO mode and it will still start both compressor and fan the same time on AC.
