A big thank you to diamonds in another thread for mentioning that they store their screen room inside their 1575 during travel.
I placed our rugs non-skid side down on the linoleum and facing up for the screen room to rest on. There is no way it is going to budge while in transit.
Also, I have it centered over the axle and on the "lighter" side of the TT (slide-out & fridge are on the other side) -
