We have the Georgetown 378 that has a slide under the canopy. We have no problem with it. You work around it. since our slide goes straight out, we added a 2ft awning cover on it with gromets. It rolles up with the awning. We attach a 9 ft staked awning to our 2 ft extension canopy and that gives plenty of space.

Thank you everyone for your response. We are still in the shopping mode and have not made a decision because the available inventory is 12+ hours away.
We will take your suggestion Ken and Velda that is awesome didn't even think of that?? We have that with our Georgie boy and haven't even used it, no need with full awning.
