Collision damage...repair questions

I wouldn't rely on anyone's "guesstimate". Contact your insurance company if you haven't. You can get their evaluation then decide if you are going to file a claim or not. From the pics it doesn't look too bad but you don't know what's underneath or if there's hidden or unseen damage. Definitely file a police report and find out of the other driver was cited.

Was there a police report? Witnesses? Pin everything down as much as possible ASAP. People will and do change their stories. You are responsible to mitigate your own damages so you need to protect it from any further damage. Tarp and tape over the damaged areas. First I would take it to the shop of your choice and get an estimate. Keep that in your back pocket for when the other persons adjuster shows up. Most adjusters have no experience with RV's and many will just tell you to get an estimate. No need to tell them how much you paid for it. That has no bearing on what it is worth now. You may have gotten a great deal and it could be worth much more. Damages add up quickly and you don't want them to automatically total it based off of what you paid for it a year ago. RV repairs are not cheap and the demand is high for good repair services. It will be in the thousands especially with the damage to the awning and if there is structural damage under the shell. If you have collision coverage and don't have time to deal with it you may consider just having your own insurance carrier handle it and subrogate to get the damages back along with your deductible.
