I was an adjuster for insurance up until about 6 months ago and left the business. But I dealt with alot of hail on RV's, Campers, Travel trailers. I'd be interested to see what the shop labor rate is. $145-160 is average in my area but I know outside there are places charging $180-220. That's the first thing I would ask, second if they charge to write an estimate and if that charge is waived if you get it repaired there. Frequently they want $100-150 to write an estimate because it's time consuming and a vast majority of people don't repair so much as turn it into insurance and pocket the money.
I also have a repair manual still where I can get detailed itemized materials and time to Remove and Install items and procedures. If you want you can PM me photos of your rig (like a sales add, one photo of each complete side, Each Corner, Roof from front facing back, Roof from back facing front, then get a few photos of the damage area. Dimensions of the complete roof. then photos of the damage area.) I can then suggest a method of repair and write an estimate for you as a guide. I would steer clear of any shop that commands more and will not provide an itemized estimate reflecting materials and the labor for each material remove and replace or R&I. I've had a few agree that they will go off my estimate and they will provide any itemization for a supplement that they may discover only to have them back out and refuse after they have done the work and threaten to take the customer to collections. Steer clear of anyone who cant give you a detailed breakdown.
