If you were going to move around like us non-stop, then the 2499 is the perfect size. Do I sometimes wish I had a slide? YES!
But I dont when we're in those back woods campgrounds where most other campers wouldnt dare go.
We have found that the Solar Panels are a huge help as they allow us to not have to worry about having to find a campground with hook-ups. We have been able to stay at a few places much longer then you normally would have if you were just running off of a normal set-up.
I cant imagine going without the lift-kit and the larger Norcold Rofridgerator, as they both allow us to stay in the back woods a little while longer.
We are thinking about getting a 2000i Generator, but havent felt the need to make the purchase yet. The Larger Thetford Toilet make sitting on the throne much more comfortable then the smaller standard unit. The only thing we both really wish we had more of is counter space, as we dont go out to eat and Cindy does all the cooking in the Covered Wagon or outside. I'd love to have one of those set-ups that attach to the side, so we could have a table that could be mounted, but we're working on that.
We might have another fresh water tank installed to make those back woods stays a little more lenghty so we dont have to worry about leaving to go refill our fresh, and not have to skimp on showers or washing up.
If you have a few years till you're ready to leave, then make sure you follow along and we can be your guinie pigs...LOL
Good Luck
Pat & Cindy
