How do i get a replacement rain top for a northwest territory silver creek 18x10 3 room tent ?

There is only generic help online and people selling them. The instruction for all tents is basically the same. Peg out the base, insert poles, lift the roof, attach fly sheet, secure guy ropes, hang the internal dividers.

Not much on that particular model, but they all work to a theme. Peg out the groundsheet and base. Slip the poles in. Attack and peg out any guy ropes and tighten them.

I have two sites that may have a manual Free User Manuals and Owners Guides ManualsOnline com
ManualsLib Makes it easy to find manuals online

Step 1 Remove the tent, poles, stakes and tent rope of the dome tent from the Northwest Territory sack. Locate a large flat area and remove any sticks and rocks from the ground. Step 2 Lay the tent fabric on the ground with the bathtub style floor face down. Pull the corners of the fabric tight and rotate the tent so the door is facing in the direction you want. Use a hammer to stake the corners in the ground. Step 3 Assemble the two long poles to their full length. The pole segments are connected by chords and will easily snap into place. Slide one pole through the diagonal sleeve on the top of the tent. Slide the other pole through the other diagonal sleeve to form an "X" with the poles. Step 4 Place the end of each pole in the corresponding grommet. The poles will bend and the shelter will be erected. Step 5 Assemble the two small poles. Slide one pole in the doorway sleeve and the other in the back window sleeve. The poles will bend slightly to create a rain peak on the door and window. Step 6 Pull the doormat tight and pound stakes through the loops on each corner. Pull the tent rope tight on the back of the tent and pound a stake through the rope loop to anchor the tent to the ground.
