If you decide on going the route of outboard generator(s), be sure to take all performance and reliability characteristics into account: price (of course), fuel consumption (long term costs of differences in burn, plus carrying the extra fuel one unit needs over the other to have it last for the length of your stay), running amps (not a lot of difference between 25 and 23.6, so add your numbers up), cleanliness of output power (both good, but onboard electronics like best over second-best), reliability (many, many real-world reviews out there on the internet), weight (if the difference between manufacturers is significant), noise factor, etc. In other words, do your homework with respect to your needs - many of the commentators above have chosen the right unit for their budget/use; how does yours match up? (And you do need to decide if you're going with one larger or two smaller generators.)
