Yea I know, damn this guy is posting alot lol. Well when the conversion is a 36 year old trailer there are alot of issues.
The rear most deck support/bumper is a mangled mess from years of God knows what. It is actually not currently structural but with my new design it will need to be. My question is current measurement is 3 1/4 inch. I am thinking go with either 3x3 box tube or 3x3 C chanel. The square tube will definitely be stronger but the C will be a little weight savings.
What are your thoughts. Also wall thickness on sides is 3/4 inch studs. Would you use square tube or c chanel for window openings.
