You provide no information for even a WAG. Age of your RV,nature and extent of damage for example. Have you pulled out your policy and read the loss settlement provisions? Anything you get here is conjecture. No need to go on the warpath with your insurance until they approach you with a settlement.
My only contribution to the discussion is unless it's a newer unit and your insurance has a purchase price or replacement cost total loss settlement rider, they will likely offer only the actual cash value of the unit. How they arrive at that figure, is open to debate. If you are not satisfied with the offer, do the laws of your state allow you to hire a public adjuster to do an independent review of the claim and render a second opinion?
Must have been a helluva pothole.........Sorry for your loss.
