I also run 2 Honda eu2000i's w/parallel kit. I made a 3 gallon extended tank for it. Easy setup. Run what you need. I have ran my 13,500 A/C with the Companion (It was my first purchase), but it was working hard and I suggest not to use it for that purpose. With the extended tank I can run longer than the eu3000i. I also have 4000 watts peak. It's nice to have 55-60 lb. generators for mobility however they can be easy to steal. Get the (pricey) metal handle covers so a thief cannot hacksaw through the plastic handle if you have it chained. Its just a deterrent like a chain. If they want it they will get it.
Now the eu3000i is a nice machine. It is definitely more quite than any other Honda out there. It is hefty so a lot more difficult to steal. Remote start is an awesome option through some vendors. If you have bed space in your truck and can leave the eu3000i in there (chained maybe), it would be convenient unless it is hot and your running A/C and you need to leave camp. A buddy of mine has one and uses a simple hoist from his garage ceiling to put it in an out of his bed.
There are pros and cons to each setup. You just have to figure out what works best for you if you want to go Honda and run A/C, microwave, etc.
