Hubba Tour 2

Since you mentioned cheap, the MSR Hubba Tour 2 has short poles and is fairly light, so is easy to pack. It can be set up quickly in the rain since the fly is attached and suspended from the clip on poles. It has a vestibule on one side where you can store your bags. Inside, the tent has room for 2 pads. In a pinch, a third person could sleep in the vestibule. There is a second door opposite the vestibule, a nice feature for 2 occupants. You definitely need to seam seal it which YouTube Reviewers were not told do before testing. It got wet without sealing and the reviewers slammed MSR for failing to test their product and making claims that their new fabric was self sealing. Oops! I decided to buy one, seam sealed it thanks to those reviews, and the ("get rid of these") price at REI was a fantastic deal. MSR stopped producing it after it was panned and shipped seam sealer to those who bought them. After a few overnight bicycle based campouts, I toured the West shore of Lake Michigan for two weeks last August and like it a lot. I slept through rain storms without problems. It's fairly light, even with the footprint. I have not shared it for weeks nor spent a rainy day in it with another person, but I can sit up facing either direction and exit either side. There is no star viewing, little insect netting, so a bit on the "close" side. Two small vents may be propped open, one on each end. A plus side of that is privacy. Touring along the Lake Michigan shoreline (damn, it's pretty!), I enjoy cooler temperatures. Some reviews complained about the lack of ventilation and condensation buildup. Yes, more netting for ventilation could help, but it is not so bad in my opinion. And if it rains, aren't all tents condensers? The vestibule is a major plus, and it's floor is half open. I can sit inside the tent with feet out of the door and put on and lace up footwear, organize and stuff bags out of the rain, zip up my rain gear, then open the vestibule to exit and load my bicycle. Alternatively, the vestibule floor is protected from rain while entering and exiting so bags may be left open, clothes laid out over them while in camp. My bags, my tent floor, and my sleeping gear all stay clean. Other than their marketing snafu/lack of field testing before release, I think MSR created a pretty nice bicycle touring tent. It is mostly red, so not an ideal color for stealth camping. I prefer to stay in State Parks or County/City campgrounds where there is drinking water, I can shower, wash clothes, charge my phone for RWGPS, etc. So, if you can find an MSR Hubba Tour 2 cheap like I did, it may work well for you as well.

We also ditched the RTT in favor of ground tents. After traveling with a ground tent for a week, we realized it was more for us. We opted to stay with a smallish ground tent. We use a MSR Hubba Tour 3 back in like 2018 and it continues to serve us well. We also have the Tour 2 if we don't want the annex. Our rigs are generally smaller, two-door SUVs, so space was a premium for us. We can just throw the tent in the back. I also have to say, drying out a RTT was an issue for us as we don't have a garage and live in the Pacific Northwest, where it rarely dries out in the winter. A simple ground tent dries out much faster.

We started our tour in Iceland on October 15th and went through to China arriving mid June. We used an MSR Hubba Tour 2. It held up to the crazy wind in Iceland. We got lucky in that winter in Europe and Turkey wasn't particularly bad that year, but honestly this tent would have been fine in anything. Had it snowed a lot we just would have needed to shake the walls in the night to keep it from sagging. The vestibule is big enough to fit 2 bikes and gear inside. It's also nice to cook in during bad weather (know the dangers of doing this so you don't kill yourself). The hardest part about winter camping over long periods is the condensation build up on the tent walls. 4 season tents have less ventilation, so they get wetter, especially when the temperature is -5 to +5. 3 season tents have better ventilation, so it's not as bad... but it's still pretty wet. A 4 season tent in the tropics .... Ungh, I'd just never put the fly on.

MSR or Big Agnes for backpacking get my vote. Mountain Hardwear also make some nice backpacking tents. Nemo and Marmot would be the next ones I look at. I love my MSR and Hardwear tent. if you want to go ultralight, just stick with a two person and you’re gonna be really snug but totally doable if you’re with a partner. I’m 6 foot three and I have slept in a two person MSR tent with another 6 foot three person. Go with the three person if you want to compromise comfort while in the tent for added weight. Chances are you will be splitting the tent up into two separate packs to offset the total weight or you’ll carry it yourself and have the other person carry other stuff to equal out the weight. It may not seem like a huge deal, but when your backpacking every little bit counts.

I've got one in my pack right now. Keeps out most mosquitos and even some rain :P

The yellow bag ones tend to be delaminated at this point, unless they were very taken care of. Hydrolysis for these older models is very strong and eminates an awful smell as the TPU breaksdown. They are similar pole geometry to the newer models but made of different grades of materials. Newer ones are lighter, less tough, and have a bit less space inside. Older models may have come with Easton composite poles and not aluminum which while lighter and spring back better under adverse conditions, tend to break in unique ways where the aluminum "male" ends that help attach the poles separate and get pushed into the pole, making them difficult to use if/when that happens.

It's my favorite tent - easy to put up, spacious for two, and freestanding without pegs if necessary. The updated versions (maybe white and red?) are lighter but I read multiple reports of people getting splinters from the fiberglass poles if I recall correctly.
