Our N2U Rockwood pup came with the RVQ grill for the outside, and having a Weber Q we really didn't need it but wished that we had a removable cooktop like our old Jayco 1006 had. So I ordered a 2-burner Stainless Steel Attwood drop-in cooktop and cover and picked up a pre-formed countertop at HD and cut it down, making it large enough to have some workspace, room for coffee maker and small enough to handle and stow beneath the dinette table. We are enjoying this mod as we have never and do not want to cook inside the pup.
