I am fortunate enough to have acquired a few different tents over my hunting and backpacking life. I am up in Montana and would say that in those summer months, I tend to camp near lakes and there are always lots of mosquitos at dusk and dawn. I would recommend two tents if you can afford it. A nice and light summer backpacking tent and then the hot tent.
In September till mid October ish (weather dependent) I'll use my backpacking tent as it's a little lighter. Then when it gets chillier I'll take out the hot tent.
There will be those early spring trips that I'll use my tipi and stove too. It's nice to have the option of the two tents. You may find a good deal on a used summer backpacking tent on craigslist or from REI. They now have an online "Resupply" where they sell used gear.
Hope this helps you out.
