I've looked many slides and decided to make my own. I already measured and will be making custom sized slides. I already bought main parts. For my basement, I will need (1) 62x52, (1)62x40, (1) 30X35 and (1) 30x 20. All parts less bolts came out to $850 including tax. I will still have to buy 3/4" plywood boards and carpet. I will keep you posted with pictures. It may be a week or tow since my Alpine is back at Saddleback RV for a few issues.
