We bought the Honda Companion first...and waited to see if we really needed to get a 2nd one. We bought the parallel cables up front, too, thinking that if we ever found ourselves ins a situation where we really needed AC there would be someone with another 2000 who might be willing to share ... and the rig with the AC could be the party trailer. We did decide we needed a 2nd one...mostly because of where we live and camp most of the time. Sometimes it just gets too warm. The best pricing is found on line through mail order.
A few more notes: (1) You CAN parallel two non-Companion Honda 2000s but you need a paralleling "box" to connect the two. It costs more and it's less "slick." The beauty of the Companion is that the paralleling is much easier with a simple set of cables that cost about $40 or so. (2) While the Companion (costing usually about $100 more than the regular model) does have a 30-amp outlet, it is a
twist-n-turn outlet...so you need a small adapter to convert the twist-n-turn female plug into a standard 30-amp female plug to accept the male 30-amp plug on your shore power cord. It also has a single 15-amp outlet, but no
12v outlet. The Standard model two regular 15-amp household plugs ...so you need a 15-amp to 30-amp adapter to accept the shore power cord's 30-amp male plug. The regular model does have a
12v outlet that you can use to charge your batteries directly, though it's not as efficient as letting your converter do that. You need a set of cable to utilize the
12v outlet as well.
It all sounds far more complicated than it really is. The Hondas are very user friendly...the care and feeding is pretty straightforward, though you do need to maintain them like you would any other small engine. That being said, they are real workhorses. I do the basic maintenance myself but take ours to a Honda shop for full maintenance when it's time. (Usually places that service Honda motor cycles also service generators.)
