What is a branch kiss, they TC hit a branch ?
Exactly. Especially when you are pretty new to RVing there is a good chance that you misjudge the profile of your RV - or forget about it altogether.
There is structural wood framing right behind the camper skin up there. It is possible that the damage is more than cosmetic. If the frame were damaged, a correct repair would involve removing the roof and skin as far as necessary.
Also, the corner lights -of which you see one in your picture- are prone to leaking under the best of circumstances. You need to make sure that the light or any of the surrounding seams do not leak. That may be difficult to find out if no external damage is visible and everything has been recently sealed over. Can someone wirh experience come along with you to assess the camper?
Lastly, I do not want to bash Travel Lite, but from what I have read about their campers, their quality seems to have been hit or miss in the past. No one can judge the state of this specific camper from here, based on a single picture. If the price is right, it can be a good deal. If it needs repairs and you are unable to DYI, it can be a very bad deal.
