With two distinct trips, one for a month and the other for 5 weeks, and having taken this tent throughout much of South Africa in many weather conditions, I feel it time to review the Jupiter 4. After 9 weeks of setting this tent up and taking it down, I am still experimenting in the set up. With wind of 20 knots I stake down the footprint then put the poles together, pole the tent in the collapsed position to the footprint. Erect the tent, as best you can in the wind, snap the fly into three corners, then insert the pole into the fly pocket back to front with the last three sections straight, the front two not inserted. Insert the fourth section with the fifth broken, and finally the final section inserted and Velcro together the front pocket, then snap the fly in the final downwind corner. Immediately stake all windward tie downs. On several occasions I had to position the vehicle as a wind block in the middle of the night as the buffeting became so excessive I was worried about pole damage. The only pole damage experienced was a slight bending of the fly pole, not such a problem.
The fly has been torn in several places because of thorn bush encounters, but with a piece of gorilla tape on both sides of the tears, it still stows in the stuff sack and has maintained its waterproof integrity. In light wind conditions, I install the pole in the fly before putting it above the tent structure for ease of installation. In any wind condition other than very light (don't forget weather can change when you least expect it to), you must stake it down- forget rocky areas!! High winds and rain were experienced and we always remained dry although with high winds at certain angles to the structure, moisture can blow under the fly and in through the screening in the upper section of the tent.
Be extremely careful of the zipper, if that fails say goodnight! The material near the zipper frayed and got stuck in the zipper and it separated. With care I managed to remove the threads, got the zipper to rejoin, then carefully burned the frays to preclude recurrence. For a larger tent I rate it 4 stars (I don't rate anything perfect), large enough for the upper 5 footer to stand and large enough for a couple of chairs and table to cook on in persistently bad weather. I always wrap the chair legs with abundant cloth to spread the weight on the tent floor. Because the poles need to be stowed in the bag prior to stuffing the tent etc. take care in windy conditions to keep it staked til the last minute, pack the stakes in the bag then stuff away! You must stuff the tent, fly, and footprint as tight as you can, there is no extra space in the stuff sack! All-in-all a fine product.
