Most CG's have showers, and the outside shower on the camper is a wand with controls. I have used mine in the past, something nice about showering outside. Hang a privacy curtain to shield neighbors.
As to Shadow Cruiser. Not my favorite, but they seem to hang in there.
At 1395 lbs it is light and probably pretty basic, but when towing what you want to tow, light is better. Can you tow that weight? I am sure you can pull anything, but can you stop i? Thing is, the way pickup trucks are rated, it is easy to go outside of limits. Should you do it? Up to you. I am likely a couple pounds over, but my truck handles it well. Would that stand up in court? Not likely.
As to not needing an extension, so long as your tow frame is long enough, thnk about tight turns. I have a V nose trailer with an ext, and I managed to touch in a backing situation that was tighter than appeared to me in the mirror.
