Good morning.
We had a 40' fifth wheel for a few years that only had the front landing gear and rear stabilizers. It was horrible for movement.
We then used the x chokes for the wheels and the front 3 leg stand under the hitch. People say the stand doesn't help but it did a good amount with us.
We have a 10 year old and a 8 year old boy and girl. The rear of the camper was a bunk house. You could feel them move in the mornings when they got up.
So then we tried what they call slide out stabilizers. Which simply go under your slide outs and you just snug them up to help. Those made a world of difference. Once we put them up most of the movement wasn't there. We put them under the main slide and one under each bunk slide.
If you do it right you don't have to worry about them hurting the slide mechanism or pushing it out of alignment.
If we were staying at a place longer than 2 days we would put them out. It we stayed longer than a week we would adjust them to account for things settling.
We had that camper for 2.5 years and never had an issue using them.
THey helped trumendously with movement.
We let them go with the old camper when we got the new one and think we may end up getting them again
