If ther is a better insulated portable on the market, I have not seen or heard of it.
They are truely a nice house and very well built.
The pole system is very easy to set up and down and they seem pretty tough as I have never bent one yet.
Many times when the snow is not to deep, I will pull the portable behind my truck while it is still set up to a new spot.
I should not do this but the portable has withstood the challenge.
You may believe the grass is greener on the other side. If you take the time to water yours, it would be just as green.
