If you're not sure what kind of bike is best for you - you can be pretty sure that a KTM isn't it.
Neither is a Husaberg.
Or most BMW's.
If you're looking for something to fart around on once you get to where you're going (ref. your comment about being able to bring it along with your 5th wheel), I'd recommend something in the 200 - 400cc range. They're cheaper to buy into, easier to load/unload, easier to pick up, have a lower seat height, are more efficient, & all around are just "easier" to live with.
If you're looking for something to cover lots of ground with in lieu of your truck/5th wheel, then the bigger bikes start making a whole lot more sense.
Just don't fall into the trap of needing the biggest/best/fastest/brand-namiest bike out there - because you don't. Several years ago I took my Husaberg (FE600) & my ex's DR200 to Mexico for a week of camping on the beach. I put more miles & hours on her DR200 than I did my Husaberg simply because it was better for picking your way through the old washed out roads & trails than the much bigger/faster 'berg. The Husaberg was somewhere north of $10,000 when new, the DR less than half that - and the DR worked better for that type of riding.
