Need help choosing generator(s)

If you can mount it, the 6500/7000i is your best option, but if you have the room twin 3000is. The reason is unless you need ac you really only need one. I have that ac on a 30ft TT and use the 3000 to run ac, otherwise we rarely use micro tytpicaly when connect to CG. Otherwise invest in solar. I have 428 watts on the roof with twin 6 volt Trojan batteries. Just did a week on the outerbeach and didnt bring the genny at all. We take showers, wash dishes, watch tv, run the wifi system as well as charge phones laptops. Wished i put solar up top earlier. That said my 3000i is now 13 years old and works like a charm. You do get what you pay for and those cheap Champions are not as quiet when they are full throttle. So noise is a consideration. So I would buy one 3000 and use the other money to put solar up top with trojan batteries. If your just charging your batteries with the 3000 I have gone 5 days before I put gas in it

PS my last pair of trojans are 13 years old and still going so it wasnt even a thought to put a pair on tis new to use TT

Happy Trails
