Hi John,
Welcome!
About the topic of a slide out.
We have an older 2350 (a 2007 model year) without the slide out which we intentionally ordered that way. It is not the popular choice, but has been the right choice for us. It has been 9 years since we bought our PC-2350 and my wife and I are still glad we don't have the slide out. We never did find value with the extra floor space that the slide out offers, but rather found greater value in having a good size dinette, much more storage, and the clean interior while traveling as we do travel a lot. Other notable benefits were the lower purchase price, 400 pounds less weight, eliminated the reliability concerns when considering our 30+ year planned ownership, better insulated, no bugs or water brought inside when bringing in the slide out, and never any water entry during wind-driven rain.
Most people love their slide out(s) which are especially appreciated when snow-birding and such, lived-in and parked for long periods of time. I do wonder if they would still love them 25 years later after everything slide out related has become tired. At the same time, most people replace their motor home long before such issues surface, so they have only good things to say about them with regards to reliability. They also emphasis resale & trade-in value because the open interior does offer a great impression, even in the used RV market.
I feel that if you generally change rigs every 10 years or so, then a PC slide out will surely serve you well. It is during the 2nd or 3rd decade when having a slide out could become more of a pain than a benefit.
