With boats or RVs the policy has been to buy a lightly used quality builder. It does not have to be the top builder but I like to have less clutter in front of me so that I can see the top builder from where I sit.
Often this means buying a less than well known brand. A builder with deep marketing pockets is not necessarily a good builder. He has simply made himself well known. If you buy from such a builder I always wonder how much of the cost to the customer is marketing cost vs actual build cost?
A good builder will get lots of referrals from happy customers. Referrals are free.
