Here is a video of a 2008 Sunseeker for those who need to learn more about theirs or are looking. He said it is a 2600 but it is a 2860 as it is identical to mine:
I have an '08 2900 and I'm getting ready for my second cross country trip to Florida...almost 14K miles so far and other than a broken
faucet handle (promptly replaced under warranty) this rig has
performed flawlessly.
For the money you can't beat the quality of a Sunseeker.
