I'm not familiar with that brand of camper, but we have a pop-up slide in and we love it. Ours is an Eagle SB thats 7 feet long. Its a great concept and works really well for us. Light weight and low profile. We have the furnace, 3-way fridge, and 2 burner stove which I consider to be very useful options. With the furnace we have camped several times in the teens and 20's and been very comfortable. The MSPR of the one you are looking at seems a little high for a pop-up, but again I'm not at all familiar with these so it might have something I'm not aware of. Some other pop-ups we looked at or have seen:
Sunlite
4wheelcamper
Apache
Palimino
and I think northland makes some.
Good luck - let me know if you have any questions.
