I have some new information:
I created a model of my camper in sketchup and calculated the square footage of the exterior panels minus the windows and such. Although my calculations are a rough guestimate, here are some figures for anyone curious about it.
Crane Composites says their filon glued to luan weighs between 15.2 oz. and 18.4 oz. per square foot depending on the thickness. At 443 square feet, the total weight of the filon and luan on my rig weighs between 421 lbs. and 509 lbs.
LP smartside says their composite siding weighs 20.5 oz. per square foot, so the lp smartside weighs in at 568 lbs.
There is only a 147 pound difference between the two. However, I am not counting the added weight of nails/screws and trim. I can only guess the nails and trim boards will add around another hundred pounds or so.
I have also created a sketchup rendering of the studs that will be used in the slide out. Sketchup allows me to create a future blueprint and also gives me a virtual space to experiment with reconstruction ideas.
As you can see in the image above, I have chosen to replace the stock single pane RV windows with actual dual pane vinyl mobile home windows manufactured by Kinro.
