The main concern with sun exposure is that over time this can weather any canvas by stretching when it is wet and shrinking as it gets hot. Most canvas tents have a UV treatment to help your tent last longer and not suffer from UV stress. When shopping for a canvas wall tent, waterproofing is not really something you should have to think about; they will all be waterproof for the most part.
I have the JW-7607 which is a 2-3 (read that as two) person tent. It has held up to kids camping in the living room and back yard, many camping trips to desert / forest / lake environments and even survived a bear “attack” with ozark tent only a small tear. In summary, this Ozark Trail 10 Person 2 Room Straight Wall Family Cabin Tent is a simple and easy to use construction in spite of such a size and height. If you are on a budget this is a tent to consider.
Weight and pack size are among the most essential factors if you plan to hike or backpack with your tent, but that’s not what canvas wall tents are for. Any tent with a heavy-duty metal frame and heavy canvas fabric is designed to be used as a basecamp, ozark trail wall tent left up for a while, or pitched reasonably close to where you park your car. The shape of your canvas wall tent will impact things like headroom, floor space, how you can position your camping cot, and how it performs in extreme weather.
If you a experienced camper like myself you would know that you have to use a tarp to cover your tent so that the water does not get inside when it rains. And you have to make sure that the zipper is closed well and also sprayed with a water repellent. But unfortunately, they are many morons out there that don’t know the first thing about camping.
The tent is also very tall with its peak height of 86 inches (218 cm), so this is a good reason to include it in my list of very tall family camping tents. Wall tents may be the most practical tent style in some regards and not so much in others. They are practical shelters in almost every way but not so practical to transport on foot. Wall tents are used alongside tepees and bell tents for special occasions like weddings and parties. They arguably provide the most headspace of all tents, so for events where people are standing up and chatting or dancing, there is nothing better.
