Hello Everyone,
I'm a newbie to this forum...I just bought my very first trailer today. I think I got it for a steal...($1000 a steal?). Don't know much about AS. I am gradually learning due to financial need. My new home REALLY needs a lot of TLC. It had been neglected for 20 years! My plan is to gut out the interior and fix the necessities (put new floor, replace broken windows, fix screen door, etc...)
I read in a thread that there is a "structural integrity to the interior so there are panels that should be left to preserve the interior structure to prevent some sort of dilapitation?
So, my question is:
How do I start gutting out the interior?
What do I need to watch for?
A wise reply on a thread said that "someone else's junk can be someone else's treasure" so it is best to label the the gutted things and sell?
Can the appliances be salvagable?
Any help will be greatly welcomed!
Oh...and I think I should post pics so that you guys and gals can get a better handle of what I'm challeged with.
