Lots of threads here findable via the search feature regarding warranties. I am usually not a fan of extended warranties, under the contention that In the long run it's cheaper to be self insured. Ability to fix stuff yourself, cash flow to absorb large unexpected expenses, etc are factors as well. That said, I do think an extended warranty can provide good stead in the case of buying a used Motorhome that could have latent and expensive problems that could not be apparent on the PDI. Using a one year term warranty in such a case can be an effective mitigation. At the one year point, then having experience and history with the RV, decide if to continue with the warranty.
I would be cautious of purchasing from a dealer. It's a big money maker for them. You can probably do better buying the warranty elsewhere.
