Make a Permanent custom Cabover Window Cover

Having an older Class C with the obsolete cabover window has given rise for concern over leaking or the glass shattering. Most Class C manufacturers have dropped the window from their line. We never open the curtains on ours as we have the reflective sunscreen silver colored sheet to help with heat or cooling. The cost to permanently remove the window and repair the hole can range from $3,500 to $6,500.
Do any of you with fiberglass experience think a cover can be fabricated in an oversized rectangle shape to cover the front window. Perhaps bolts for mounting it can be impregnated within the cover. A good rubber or butyl seal could be applied on the edges. Then have a template for drilling holes thru to the inside where washers and nuts can be used to secure it. The orignal glass and frame can stay in and the curtains will cover the glass and the bolts, washers and nuts. Perhaps, some sort of plug can be made so you can insert in the bolt holes in the evnt you want to remove the fiberglass cover.
This would look something like the rock/debris shield mounted on the front of TTs to prevent damage.
Any thoughts or suggestions?

  • Found a fiberglass truck tonneau cover manufacturer who can custom make it.

    IMHO, JMHO. Drilling, cutting, opening up the cab over is just asking for more problems and no matter how hard you try it is just going to compound any leaking problem that can occur. Especially if you start changing the structure of the cab over. Just saying.


    Yep it sounds like one of those "Fix it till it's broke" situations.

    Good Luck.
  • No cutting or opening it up, only drilling 8- 5/16" holes surrounding the window frame for the fastening bolts. Could even use some sort of raised wall pass thru device for cables. Sealed it to prevent any leaking at the bolts if water should enter thru the outter seal. Add weap holes at the bottom for draining if water does come in thru the outter seals.

    Take out the window, frame in the opening, glue on a piece of filon using some 3M marine adhesive, and finish off the inside. The added piece of filon would overlap the existing skin for an inch or two. At least this is what I've been considering.

    Ok, but how will it look? From other posts, I see that there may not be any kind of frame to attach your frame to. Some look like there is just filon, luan sheet, styrofoam and fabric. No real support.
    I saw a window removed from a Winnebago by a local RV shop. They did a terrible job and it leaked at the side seam. The inside looked even worse with the curtains gone and a patch job.
    Maybe a custom boat shop could make one up?

  • I'm looking for something that looks good and doesn't draw attention. Something along the lines of a truck bed fiberglass cover. A used trailer rock guard probably isn't going to be the correct size and may or may not be easy to attach.

  • can't you buy a cover that TTs have over their front window. there have been posts of businesses that sell old/salvage parts.
