I doubt your extended warranty will cover you.
My experience with an RV extended warranty is that they will leave you hanging high and dry when on the road!
Which they did to us while over 1000 miles from home, and an over $1000 repair bill that was basically a bandaid to get us home (over $3000 repair when we got home, so over $4000 total for a new trailer with less than 5000 miles on it)!
Read the fine print . . . and carry EVERY SINGLE RECEIPT while on the road for everything you've ever purchased or for work you've ever had done to your RV.
And even doing this will not guaranty that they will cover said issues.
Be sure to read the fine print, plus carry the lemon juice to make the invisible ink appear before signing on the dotted line of an extended warranty.
They are almost always a rip off!
