I traded my 18' ultra-lite in on my new Eagle 266RKS (same length as the 26bh). Like you, I was anxious about backing it into a tight spot. I find the longer trailer much easier
to back up than the old, smaller one. With the old trailer, by the time I could see the trailer side in the side-view mirror, it was already too late to turn it easily. Backing would take several attempts just to get it straight. The longer trailer is easier to see in the side-view mirrors, so I can start my turning adjustments earlier, making them less drastic. Just takes a few times backing to figure out where the pivot point is.
Yes, the longer trailer will nix a few campsites, but not that many. One word of caution, however: if you have a 30' trailer and a 30' driveway, watch out for the gutter on the front of your garage. (Don't ask me how I know!)
Neverenoftackle: I agree with you about t.v. location. The television in the 26bh is mounted on the wall above the rear dinette bench. That makes for a "straight-on" view from the sofa.
