What is the actual weight of your River country tent? The website is saying it weighs more then the tent I might run.
Just weighed it for you. I have the v2 (the v2.2 is 2oz lighter I believe). Packed including the bag and 50' z-ing quick deploy ridgeline, 3x 6" bank-line attachments with Dutchware titanium "wasps" and 8x OBKJJ (some generic brand) aluminum "tent nails" was 2lbs 14.5oz.
Bear in mind advertised weights don't count the trekking poles. My packed weight includes a ridgeline, which I always use, and I only carry one pole. I find one is enough for my hunting style and I have a "V Yoke MB' mounted on it to use as a rifle monopod. The way I see it, my overall "load" weight from carrying a single pole and not needing a bipod on my rifle is a significant further weight savings.
In terms of height this is less tall than the tipi-shaped competitors, but I can sit upright along the centerline so it's fine by me. It's also very long - about 7.5'. I can fit all my hunt and camp gear inside with room to spare, and 2 adults (if my wife joins me) still works while still having some gear/boot space at your feet or above your head.
This tent does not come with a rain fly, but since my Anyoo poncho doubles as a tarp I can use that when needed, so there's another weight savings. I've never had any condensation problems leaving the vents closed, but it does have vents if you need them. I like that it has a full "bathtub" floor that comes up the sides about 3". I've never bothered trenching around the edge of my tent for water runoff.
This is not a perfect tent, but it's cheap, has lasted me 4 seasons of moderate use so far with no signs of wear, and is very light. IMO, if you're looking for lightweight tents and don't want to drop $500 on something crazy, this is definitely something to consider.
Overall I'd say as an individual component the Lanshan 1 is lighter. But as a complete camp setup when you consider the other components, it may be worth considering. For folks where this fits their style, you can get a bigger tent with a lower overall "system weight" depending on how you mix and match things.
