Rich,
Everyone is making excellent points. I'll add a few of my own.
When shopping for our replacement motor home in 2006/2007, I was attracted to a local RV tent sale. There I seen a brand new short class A with an inviting $59,000 sticker on the window. It looked sharp from a distance, but then I stepped inside. Put plainly, it was put together very poorly and with cheap materials. I could see it wouldn't hold up to the beating of being driven for lots of miles. Another strange phenomena was that I could not breathe inside it. I actually felt faint and had to leave before I passed out. There was an outgassing of chemicals from the construction process that had me getting dizzy. Maybe it was from the particle board formaldehyde or adhesives or something else, or a bunch of chemical outgassing in combination. One thing for sure, I couldn't buy that rig if I wanted to. I'd die inside it.
Around that time, a family member had us sleep inside his 5th wheel. That too had a similar odor and effect on me. It was an older trailer which I had assumed much of such chemical outgassing was over with, but such remnants had me wake up with a splitting headache the next morning even though we had the windows open all night.
We've had no such chemical outgassing issues with our PC.
Another matter all together different. Unlike the masses here and abroad, my wife and I don't value a slide out simply to gain more open floor space. The extra cost to purchase, the extra 400 pounds per slide out, the extra mechanical complexity & seals with age will become a liability, the loss of interior storage, the cold heat noise bug and wind driven rain infiltrations, all combined doesn't justify the benefit. We also highly value the dinette (with memory foam cushions) which cannot be installed in many of the PC slide outs. It does help to have our 3rd captain seat for a place to kick back and relax, today that is a Euro chair. If you feel as we do, a no-slide out is an option for you to consider.
The only other benefit to a slide out would be for resale benefits as most people are initially attracted to them when shopping for a motor home. They look impressive when opened up inside.....great eye candy.
I do need to include here that we travel without children or dogs. If we had more bodies inside, I'd think the extra floor space would be of great value to us. But for just the two of us, ordering our rig with a slide out would be regretful. We elected to spend that money on a full body paint job which we like very much.
