It sounds like you are looking for a freestanding two pole crossover with a side entry. And that you plan to be out in the winter, which probably means snow. If so, then a two pole cross over with full length poles would be more likely to support a lot of snow without breaking or bending just one pole, as could be the case with the MSR’s and their progeny which are based on one hoop with a number of struts. Two full length poles are stronger, and if you anticipate major dumps of concrete-like snow, as we had in the NE this winter, even stronger poles can be obtained from Tent Pole Technologies, or Quest Outfitters if you are handy and can do some of the work.
A very light and good cross over is the Big Sky Evolution, with internal poles, so much of the snow can slide off your tent canopy. Most of the other Big Skies use external poles that can create a snow fence effect, and hasten tent collapse. And the Evolution is very light, a concern you mentioned. Unfortunately, Big Sky can’t keep up with orders, so it might be next winter before you get one. In the meantime, their are similar, but heavier cheap tents of this type, like the Kelty Discovery Trail 1, for a little over $100.
But if I were looking for something more permanent, I’d wait on Big Sky. The free standing Big Agnes tents (Tiger Wall etc) are popular, but what is with the 1200mm HH fabric, which will become even less water resistant with use. With the cottage manufacturers, like Sling Fin, and possibly with Trekker Tent, one must wait a bit, and winter should be gone in less than a couple months.
There are some nice tents of this type made abroad, like the One Planet Goondie, and they are expensive, just as likely to be out of stock, and heavier than the Big Skies. I waited for one, and then spent more months replacing the heavy floor and remodeling the rear vestibule to increase space. For me it is a hobby, but for others, the delays are often worth the wait.
Sorry I can’t tell you much about the Trekkertent. Maybe someone with some experience will respond. So hope this note is helpful, and may encourage others to reply. Happy Trails.
