On our trip here to Nappanee, we stayed at two Cabela's parking lots with no issues. We located the coach in a parking slot adjacent to an area where the bedroom slide (the only one we opened) did not extend over a parking lane. Worked fine.
One tip for Cabela's RV parking lots; don't park in the lane adjacent to the water/sewer station. People were pulling through next to the coach to get water or dump their tanks and Cabela's parking lanes are VERY narrow. Some of the folks using the facilities were pulling horse trainers and big 5th wheels...and, they didn't seem very concerned about how close they got to your coach. After the second episode, we moved to the other side of the lot. It wasn't as good a location but, at least, we didn't have to worry about losing the side of our coach!
Oh, and expect rigs to continue to arrive until about midnight. Didn't cause us a problem but we were surprised to see several more units there in the morning than we saw when we went to bed at about 10:00 pm.
