If you do a lot of dry camping, and wish to keep generator run time to a minimum, i would suggest upgrading your stock converter/charger. Many RV's come with the WFCO units which work fine for many people but do not charge batteries very fast. If you are wanting a fast charge, look for 55-75amp models from good brands like progressive dynamics, Iota, powermax. etc. I recently upgraded my converter and I am pleased with it. If you only occasionally battery charge from a generator then it may be a waste of money though.
Example - If your 220 amp battery bank is at 50% charge (110amps missing from batteries) it would take that honda eu2000 with the DC charge cable, at 8amps, over 12 hrs to bring them back up to 90% capacity.
A quality 75amp converter/charger would take 1.5 - 2 hrs to bring to 90% charge.
