I keep the top bunk in the up position. It's not to bad entering the lower bunk, just sit close to the head swing you feet in and there you go. The bath room is functional. Its great for night time calls the shower is a little spacey but most of the time we use the campground bathrooms. I would not call them great but you have one onboard.
As for the towing, I have a 2009 GMC 1500 serria that came with a tow package. The trailer towed with a small swishy feeling, not bad but I knew I was making some 1,000 mile runs and I added a towing hitch, now no movement and I can pull as fast as I can afford( gas&cops).
I live about 50 miles east of Joplin, I44 exit 58, my unit is still out, we use it as a spare bed room during the Holidays. Let me know if you want to see it or send me a private message and we can talk. The other unit I really like is the EDGE 192. I think it has a real good floor plan. That's the one I would have if I didn't already own this one.
