Cost to prostreet....approx?

I do all my own work, so I have no idea what the labor cost would be to "pro street" the interior, but I will tell you that it's a lot of labor. When I did mine, I used steel instead of aluminum. Why, you ask? For one reason, I never learned to weld aluminum. #2) Aluminum dents easily.
#3) I feel that the steel floors and tubs offer better strength in tying all the pieces together. My 2 cents.
