A couple of data points.
1. You must be your own best advocate. We've put more than 54k miles on our coach in 3.5 years, averaging 8 months each year. We've had issues but fixed each. Thor has been very helpful. I outlined the process we've used. It is here:

2. The pricing and percentages you've been given are spot on. I'd say a minimum of 30% but upwards to 40% of MSRP are your aiming points. Some folks will advise to buy used others advise to buy new. Unless we could buy way under market, we are buying new. I am always skeptical of buying used - always think I am gonna get the rig that someone traded in because they had so many issues. At least with a 1 year warranty, I know from experience Thor will stand behind the issues.
Just our way to roll.
