The MSRP for our RV as configured (we opted for most features) was around $127,000. We paid around $91,000. You can typically get 25-30% off MSRP. Grand Design has a build and price tool that was very helpful. We used that to build out the RV we wanted, then shopped the build around to get the best deal.
The truck was around $60,000. So, we're all-in for about $150,000.
