Help with Possible Upgrade to 5th Wheel

I'm fortunate that where I bought my first camper from, the sale was done directly with the owner. Since then, the owner and I have become pretty good friends so I know I will get a fair deal. Obviously he will make some money but I won't leave the dealership feeling like I was bent over. My choices are what brands he sells so I would rather stick to one of those rather than going elsewhere. I'm loyal that way.
