I would like to add to Milkman55's insight that you/we need to accommodate in our expectations: the supply chains have been stretched to breaking point by Covid such that the planned production of most RVs will be held up because of the lack of crucial parts. Compressors for refrigerators, LEDs, tires, switches, fiberglass, adhesives - the list is lengthy. So even the dealer inventory planning will be late. Sometimes it will be a week or so, often longer.
