Considering our shop charges a flat rate of $135 per hour on RV related repairs, I's say it's reasonable, however, you can do that yourself. I'm 68 and I would have no issues removing old caulk and resealing the seams, popping clearance light fixtures and resealing them or recaulking windows. It's not hard, materials are available online and some Lowes have them and tools are basic. Scraper or stiff putty knife and a screwdriver or square drive bit for drive screws and some rime on your part.
Best part about doing it yourself is, you'll know it's done right because you did it.
