Ok just had to ask. If you are comfortable with a 5er and its towing traits no real reason not to upgrade. Quick check of RV Trader for that unit shows a range of prices from a low of 45K to a high of 61K.
As you said, your not a newbie anymore, so you know that dealer add ons and fees are a huge pert of the issue. What did your dealer have on those?
Everything is negotiable including the transportation and documentation fees, work them all. I guarantee the dealer is working all those numbers.
You can replace a roof AC and a couple of tires for the extra $43,000 he wants, make him earn it.
