Outdoors RV Creekside in Eastern US? Creekside vs Nash

We have a Creekside it is built middle of the road.The floors are OSB.Noticed after we got it sales dept said it was plywood(maybe a misunderstanding) Somethings don,t make sense like any RV. But we like the unit because of the heated tanks and heavier axles and tires than the other makes with same GVW .I'm sure that if you get the double window you get a quieter rig. We don't have double windows but it is a far quieter rig than our old Prowler.
