Hi. Very unlikely that it's the slide is doing that. Rather it is simple construction residues that are eventually cleaned up. I push videos out very quickly and operate on my own. I frequently pull the unit in and do the video shortly after arrival on the lot -just as fast as I can and this means the unit is not yet "PDIed" (prepped) at this point. Therefore don't be alarmed to see the occasional construction residues if you look closely at the videos. Apologies. You can really rely on the outstanding Grand Design warranty and excellent track record of supporting many very happy customers.
YES! When Bish's orders these units in, we generally go with the popular option of the theatre seats. As an option the theatre seats cost a little more than the tri-fold sofa. The unit definitely can be ordered in without the theatre seating option. Reach us toll-free at (866) RV-CENTER
