I was one of those folks that tried to keep the camper from moving as much as possible. In my earlier RV ownership years, I tried extra jacks, extra boards, supports all kind of thing. It never really cleared up the wiggle completely, but I suppose it made me feel better.
Then, my wife and I went on a Carnival Cruise around 2008 (I think). Now that was a big ship, but every now and then you could feel the movement. I never got sea sick or anything, and after a while kind of liked it... began to enjoy those moments.
One night laying in bed, I realized I could feel the movement of the ship. It was soooooo cool! I kept waking up my wife ... "Did you feel that!" After a while I'm surprised she didn't slug me!
Well, when we returned home and were in the camper the next time, it got real windy. And even though I had the jacks down, we could still feel the camper rocking. AND it was soooo cool! It reminded me of the ship!
I actually went outside in the middle of the night and raised all the jacks, and let it rock in the wind while we slept. Well..... "she" slept, I laid there and enjoyed the rocking.
Ever since then, It's not bothered either of us. Sometime we don't even bother putting the jacks down any more. It brings back a really nice memory ever time I feel the movement now.
Edit: You know, they are called "RV's" (Recreational Vehicles). "Vehicles" means ... movement. And you know ... "Travel Trailers" have the word "Travel" in there. Both "Vehicle" and "Travel" indicate "movement"! When you feel that rocking in your RV ... that's your RV or TT telling you ... "Hey Mom! Hay Dad! ... let's getty-up and go and do some more travelin'! I'm ready! I want to get a-rocking down that road!" (you do know your camper has it's own personality!.... right?)
