When we were looking for our current trailer, we were upgrading from a trailer without a slide to one with a slide. We did plenty of research and we don't use the slide portion when it is retracted. We prop the bathroom door open when putting the slide in so if we needed to make a pitstop (with grandkids it is not if but rather when), we can still use the bathroom.
My dad purchased a new trailer a couple years ago and he did not get one with slide. His reasoning (he is 87) is that he often goes out to secluded areas by himself. He felt that if he had a problem with a slide, he would not have any help to get it in.
His last camping trip last fall, he had lower than expected temperatures and ended up running the furnace a bunch. His single battery would not last more than two hours. He has an onboard generator and when the main batter died, his generator would not start.. if he had a slide to put in before he headed home, it would have greatly complicated things.
With all that said, it really is personal preference (dad likes our trailer, just not wanting one for himself) on whether you get a slide.
Will you be camping without power? (remember, you need a well charged battery to run slide)
Do you go out by yourself in remote areas?
Get what you want (your wife wants).
