Can you help me figure out the right motorhome?

HOM, from what you stated, you are going to spend somewhere between $200,000-$500,000 for a used top of the line 3-5 yrs. old motorhome. Newmar's are certainly nice.

Have you thought about a used Newell, Foretravel or Prevost? Now, these upper end coaches will put you back to about 10 yrs. old. But the solid chassis is something to consider.

Good luck,
MM.
