well i decided it time for new portable. i went with the GT fortress.(wanted more room) my XLTwin has been great even made some mods to it. which is why i stayed with frabill. if i had more $$$$ i would have gone with R2-tec. unfortantly no one had them in stock so i couldnt see one in person. only website pics. would be great if anyone that has/had one give pros/cons or some pics in use that would be great. supposed to be in by end of week. and then week later off to LOW!!!
(there will be a modded ranger XLTwin in classifieds really soon!!)

Pros
Lots of room
Very comfortable chairs
Sets up fast
Never frosts up on the walls
Warms up very fast inside
Windows are velcrowed in and can be replaced
Big sled with lots of room in it
If i ever need another one it would be insulated again
Cons
In -40 temps the sled will frost up on the inside(back wall)with the wind at the back.
If you use a big buddy heater and turn it on hi,it warms up so fast you will be peeling the window out trying to get some cool air.
The inside material is white.Some of the aluminum from the poles gets on the material and is hard to get it off.
Here`s a few pictures

pretty sure Joe's in St.Paul has the insulated Frabill on the showroom floor

well i got the fortress put together today! man, what a task!! it took 5 hours!!!! am i an idiot or is that normal? i love the size. lot bigger then my ranger xltwin. only thing i have to finish is putting on the storm guard trim. then its off to LOW next week!
