Rumpus 4

Sundome is much lower quality than the other options. If you're looking at Coleman, step up to at least the Skydome. Funny enough I was going to recommend the Basecamp. Ventilation isn't great with the fly on but that's very common with cheap tents. I like wooded campsites anyway where you can angle the mesh portions of the tent into the trees and keep the non-mesh facing the walkway for privacy. Kelty kinda owns the cheap-but-mostly-quality space. The Discovery Trail 3P is very meshy which helps with ventilation but still a lack of fly vents. If you can stretch the budget or find a good sale, the Kelty Rumpus 4 is a killer deal. Lots of ventilation, vented fly, and a great vestibule that you can keep wide open to help with ventilation. The Teton looks fine. I like the look of the higher denier fabric and vented fly. Teton has historically been a cheap crap brand but they've really made some improvements in the last few years. I don't love that their "lifetime warranty" explicitly mentions that things like bent poles are considered normal wear. The marmot is an excellent option if you can get it at a good price and you're genuinely okay with a 2p.

Kelty Rumpus, 4 or 6 person models check off most of your needs and desires. Huge porch area for the doggo. Partially orange in color. Easy to setup even single handed( i have experience at this). Fits your budget pretty close, 4 person is under $300, 6 person size a little over if it's not on sale. Strong aluminum alloy poles.

I came here to say the kelty rumpus! It was incredibly easy to set up and it rained when we camped and we stayed very dry!

I have had a normal kelty 4 man and the daydreamer 6. The 4 held up great for almost a decade of use (~6 trips a year with that tent) before we needed more space and upgraded. The day dreamer 6 is pitch black inside which is great for getting kids/dogs to sleep in later than sunrise. The thick fly to keep out light definitely adds a pound or two to the day dreamer vs a normal tent.

it fits my kelty 6 comfortably with space on the size. it was very tight with my kelty 4

I have two tents (both kelty brand) a two person for solo backpacking/short trips where bad weather isn’t forecast and a 4 person for trips where I have another person in the tent with me or I plan on having to spend more time in the tent. Totally a reasonable move and the bigger tents really aren’t usually much harder to set up unless you have some huge 10 person multi room situation

My BF and I have 7 different tents and our favorite one is the 4-person Kelty tent that I bought for myself when I was 17-18 years old. That makes it 36-37 years old. It’s not the same shape as the one OP covets but it has the same basic options with a large back window screen and the zipper screen entrance with the additional layer of solid fabric. Unfortunately it’s so old and the fabric is becoming very brittle and fragile. Wish they still made tents like they used to.
