Few years ago I bought a Honda EU2000i for my Vixen thinking it would be enough power. Only blem wit that was that the 1986 mode central ac under the dinette really made it grunt. One of the VOA members had a kit that did three things:
1) turned both the coach and the compressor fan on continuously.
2) added a "hard start" capacitor
3) added a time delay so the compressor did not start until the fans had been on for a minute.
Honda still grunted (could not use ECO mode) but did the job.
TM needs more. For one thing it appears you cannot turn off the converter. Secondly instead of a 600W microwave it has a 1100W. It also has a electric water heater (Vixen has a diesel furnace). And a few other things so felt I needed
More Power. That said I could get $50 off the $1100 EU2000 companion. but would need to carry 2.
Or the 2500/2200W HF "Predator" #61169 was on sale (everything at HF goes on sale sometime) for $499. My feeling was that if the 2000/1600 Honda was grunting, a 2500/2200 gen should take in stride. Did chicken out a bit and bought the $129 2 year extended service contract.
OK so this afternoon I gave it a prep and while dealing with the hub issue (pretty sure someone with a really big air gun put metric lug nuts on the SAE studs) let it idle for an hour or so before connecting to the TM then let it run for another hour at very light load before heating some water in the Microwave as a 1100W test. Ran fine and putting out 118-119VAC.
Might mention I pulled it though a number of times with the fuel off to circulate the oil then turned on & waited a few seconds for flow to happen then pulled. First pull popped a little, second pull started.
Then turned on the ac fan and ran on high for a while before the final test: turned the ac on. First try NG, voltage dropped to 45vac and the gen stalled. Did twice.
OK so not idea what the ac is, have not found a label & could not find my special split lead to measure loads above 10A so brought out the little Honda.
Let run at idle a bit to warm up and turned off the ECO mode. Ran ac fan on high for a bit then switched to ac. Honda grunted and voltage dropped to 65VAC then I heard the Honda dig in, compressor started, and cool air flowed.
Back at the Predator I pulled the cover and moved all of the linkages through their ranges to eliminate any sticktion then told it to learn from the Honda and what would happen if it stayed recalcitrant.
Started again and let settle before trial. This time the voltage only dropped to about 95VAC and for the first time I heard it shoulder the load coming back to 118v quickly and cold air blowing. Was running easier than the Honda did. I let it stay on and go through several cycles while watching the voltmeter when the compressor kicked in. Took the load much easier than the Honda.
So after about four hours and a bit of jiggling it is doing exactly what I expected.
May need to turn the house battery sideways but then the gen should fit in that compartment. It is about 20lbs heavier than the Honda but not much louder even when loaded, about enough to match a 25% larger engine rated for 37% more power. And about half the price. Much quieter than a Coleman Powermate I wound up giving away as a wedding present. Much quieter than the 800W 2 stroke I also have. Too bad I cannot just gang them all together.
Longetivity ? Unknown at this point, reviews are all over the place which is typical and the reason for the extended service contract (first one I ever bought from HF.
If I get everything together and figure out how to turn around in the back yard will be at Lake Louise this weekend for more "testing".
