Have to agree with the others. There is a long history on this forum of really unhappy owners, as a result of this company producing substandard products, and doing little to address the issues. Now, this type of statement will typically draw the defenders out of the woodwork with claims that THEIR Gulfstream is the greatest thing since the invention of the wheel, but take it for what it's worth.
At some point it becomes pretty funny. There are in fact going to be a limited number of satisfied customers of any RV manufacturer, no matter how poor the product actually is. That said, the interwebs tends to draw out the folks that would stand next to a rotted, moldy, motorhome, as it was burning to the ground, and say, "yea, it's been a great coach, we are really happy" LOL
EDIT: keep in mind that this company no long produces class A units, and that they had major issues with rigs that were so poorly engineered and built that the diesel engine overheats constantly due to the confined, nearly non-serviceable engine bay that fails to allow for proper cooling.
