Outdoors RV Black Rock 23BKSYou are going to want a slide to open up the space in the trailer for a family of 5. You could also consider looking for something slightly bigger so search for trailers that have designations of 25BHS/26BHS or BKS (usually BHS = BunkHouse Slide, BKS = BunKhouse Slide). The 25/26 trailers will generally have a point to bumper length of around 30'. Along with the GVWR on those 25/26 trailers, it should be no problem for your currently listed TV but they will exceed the total length you've listed in your OP.
