I have a 2006 Host Double Slide Ranier that was built at the end of 2005. Our slides have been fine, but from what I remember, they changed their slide design several times up to that point. You can search here and possibly owner groups to hear about other brand issues. It seems to me that more people complain about Arctic Fox and Lance slide adjustment and breakage but maybe that’s because they sell the most.
It’s possible to break anything. Sure, there are some bad designs, but mine isn’t. I can’t vouch for other designs. At the same time, a poster here was able to break a Host that is the same model as mine. Then, their “fix” seemed to be quite a hack, but they liked it. I haven’t seen a post from them lately, so maybe they traded or maybe it is doing fine.
No brand has a lot of extra structure in a truck camper. So, if there is a lot of weight in the slide, and/or it’s out of level, you will likely have more issues. If you plan to stuff the dinette drawers with heavy weight and you/spouse/other occupants add up to significant weight you have more chance to have more issues.
On the other hand, we’ve never regretted having ours. The second slide makes a big difference. Maybe it doesn’t matter to you. I find most but not all nonslide campers to be a tunnel. I don’t personally like that style.
I’d personally would never own a Bigfoot. In that style, I’d buy a Northern Lite because their floorplans are significantly more usable for how we use a truck camper.
