Dan (Op) another thing to consider is registration for warranty. My DW was slow for the time allowed, and yes we had the battery fail and a month later a regulator module fail.
We were screwed for warranty repair, but as I am very handy and could diagnose and do the repair myself, WH sent the regulator fairly and timely. ( small $ )
In Jan. 2019 in the Q ( Quartsite, Az,) at the ONAN demo tent there was the exact same genny in Onan green. Vs WH blue.
If Onan, a very reputable co., has put their name on anothers product, theres a feather in their cap. Thats the one I'd put faith in.
That auto choke issue wuold have to be better and a larger faster cranking battery for me to recommend this genny. The remote start is worthless, even in nice weather it often takes 2-8 start cycles for the genny to catch and power up. In cold weather Im having to pull the rope. The electric starter even with the big battery just doesnt crank the motor fast enough
I would enquire if these issues have been addressed before buying. For us,the power is clean responsive to resistance load , not to demand load. As an advertised 3600w continuous 4500 w peak , we have concerns the 3600 w is iffy the 4500w peaks just arent there. , it will not start up power a 2nd A/C the demand load is higher than it can respond to even when in high , not eco mode.
