When you bring in the trade they're going to look it over. If they find a surprise such as delam or some other large issue you can bet dollars to donuts they'll be wanting to adjust the trade in value.
Funny thing is they put the trade-in price in the sales sheet when we signed the agreement to purchase the new camper the other day. I guess I have contractually agreed on the sales price of the new camper and they contractually agreed on the trade-in price without even seeing the trailer.
In retrospect, I wished we would have put this up for sale long before winter hit here in the Midwest. I had the TT listed for over a month on Facebook marketplace and Craigslist with very little interest. I had forgotten about my Craigslist ad until someone contacted me on it a few days after I had agreed to trade it in. I've learned from this experience but I'm going to pay for it.
