Our MOHO came with a pass thru slide already installed in a bay. It is the version sold by PPL Motorhomes, out of Texas. I took control of it right away!
Have a 5 drawer tool box, and a LOT of power tools bhind it, and it seems to hold the weight fine. I have used it over a year, and traveled many miles, narry so much as a problem...This model slide is cheaper than CW, but, you have to supply your own wood flooring material, still, a nice addition...they come in several widths, as well as lenght, check 'em out...
Back to a 5'er after 4 yrs fulltime.
