Replacing an RV window usually comes down to two questions: does the new unit fit the opening, and what parts do you actually need? If you have a Lippert-style window, the 806621 complete kit is a direct replacement with black dark tint. If you need a more universal solution, the 24x36 vertical sliding window with screen offers a standard size with aluminum alloy and tempered glass. The listed prices are $74.99 and $143.66, so the choice also affects your budget. Here is how they stack up.
Quick Verdict
The 806621 kit is the direct-fit route for a Lippert replacement, but it comes with an open-box, new-other condition. The Universal 24x36 window is a new, more broadly sized option that includes a screen and mounting accessories.

Product Notes
806621 RV Window Complete Kit Replacement for Lippert Black Dark Tint
The main appeal of the 806621 kit is the direct Lippert-compatible fit. You don't have to adapt a generic window to your opening, and the black dark tint is built into the replacement window. The listing condition is 'New other (see details),' and the description says it appears new in an open box and that the seller isn't the original owner. That's the trade-off: you're getting a direct replacement path, but you should inspect the contents and understand the return process before you finalize the purchase. For RV owners who already have a Lippert window and prefer the direct replacement route, this kit simplifies the shopping decision. The open-box status means it probably isn't a sealed retail package, so checking for all included pieces matters.
Universal Rv Window 24\"x36\" Vertical Sliding Replacement Window With Screen
The Universal 24x36 vertical sliding window is a more versatile choice. It's a new unit with a screen, and the package includes a trim ring, an English manual, and other mounting accessories. The listed material is aluminum alloy with tempered glass, and the fit details specify a 24 by 36 inch mounting hole size with a wall thickness range of 3 to 6 mm for forward mounting. Because it's universal, you'll need to verify these measurements against your own RV opening before ordering. The universal sizing also means there's no specific Lippert compatibility to rely on, so careful measuring is part of the job.
Final Choice by Use Case
Choose the 806621 kit if you have a Lippert window opening and want black dark tint without adapting a generic window. Choose the Universal 24x36 if you need a screen-equipped vertical slider and are ready to verify your opening against a 24 by 36 mounting hole size.
