We just bought a 2011 Sunseeker 3010DS and love it. There are a couple of things that I could suggest as improvements. These may have been taken care of in newer models, so if they have, just ignore this suggestion.
We had a Class B Gulfstream Vista Cruiser and just inside the door was a switch to let you turn on the inside lights without entering the coach. This was really handy at night. On our coach, you can turn on the patio light from down by the steps, but you have to get inside and fumble around or use a flashlight to get to any lights inside.
The other issue is with the switch for the bedroom slide. It is about the same level as the light switch and closer to the bed. I keep wanting to use it to turn on the lights. I was also worried about our three year old grandson playing on the bed and kicking the switch with his feet. He didn't but I was continually watching him to make sure that he didn't touch that switch. the other slide switch is on a wall panel that would be difficult to mistake or for kids to get to. I may put some kind of cover over it so that I don't get up in the dark and forget I am not at home. At least, you have to hold it in to make the slide move. :-)
The U-Shaped dinette takes some getting used to, but the bed it makes is actually pretty decent. The table seems a little high, but I suppose we could cut the table legs off to adjust that. Maybe some adjustable legs would help.
Thanks so much for your participation in this forum. It's nice to know you guys care about our suggestions and satisfaction.
