HELP! Thetford RV Toilet Question

From what I have read and heard about you should not put braces of any kind under the slideouts. I think it is normal for them to look like they are leaning a little. You could do damage to your slideout mechanism if you do. They could bend even a little and you would have a heck of a time getting them in. If you have any manuals for your rig, you may want to read through it. Or download one on your computer. There is also a lot of information out there for new RV owners to access. Our trailer is almost 10 years old and we have never braced the slideouts and have been lucky to not have any major problems with our travel trailer. We do regular checking of seams, the mechanics and appliances and try to keep it clean. It is a learning process, so we try to keep on top of it.
