installing 3 of them, would you do it or have it done by rv shop? none currently on unit, so it would be the full set up, rail, brackets and all. im fairly skilled in most but not sure of this project.
We just had three installed yesterday by a mobile RV tech I like to use. I helped him when needed and it took about 5 hours. The longest one also had a cradle installed in the middle because of the length. You will need a second set of hands but after watching him I would feel comfortable installing them. Just take your time and take good measurements and caulk all the holes good.
