New 5th wheel purchase. I think we have a lemon, need advice

During our. PDI I saw a few small items that were correct at that time.. I was leaving the following Friday for a 3 weeks trip to Florida, The dealer made me a follow up appointment for the first week we get back from our trip. This way they could install the 1 item we purchased that could not get in, and to correct any issues that we may find during our trip..

We dropped it off on a Thursday, went back that Saturday to get it
Can't ask for more than that
