Like many, I’m looking forward to more info on the Burp. To be honest, it’s just an annoyance, and the longer I use the unit, the less it bothers me. My lawnmower tends to do it as well when at idle, and I don’t even notice it really unless I think about it.
As for using the generator to charge the batteries on an RV. That’s the primary use I have for mine, and most of the time it does pretty well. If and when I get more time, and a little bored I’ll have to look closer as to what is going on. Most of the time, I try not to let my two group 24’s get below 12.1 volts, and as long as I do that, I don’t have any issues plugging the TT into the 2000i, as long as I take the generator out of Eco mode when I first plug it in. Once it’s stabilized, going to ECO doesn’t matter. You also have to kick it up on high is you’re going to try and use a hairdryer or something along those lines. The only problem I have is if and when the batteries are low enough that my converter tries to kick up on high for battery charge instead of the mid 13 volt range it normally selects. When it tries to start on high immediately, it kicks the overload on my little champion. Using a stand alone charger powered by the generator for a couple minutes puts enough of a surface charge on the batts that the convertor doesn’t try to run full blast and then you can plug the trailer in..
As for how long a day I have to run the generator, I always boondock, rarely if ever run the furnace, and find I can get by with an hour or two a day, and even skip a day here and there. We don’t run much that draws on the batteries, but even then if I have my refrigerator running, I’m generally drawing somewhere in the 1.5 to 1.7 amp range just from the fridge, CO2 detector etc. Seems my 2011 Springdale is much more of a parasitic power hog than anything I’ve owned in the past
