PopUp: One tire threw it tread at 3 yrs taking out the plastic wheel well and dumping our pots-n-pans out on the highway. Other than that, flipped the axles for 4x4 ground clearance and enjoyed the heck of that thing. Very affordable. All-in-all we really got a lot of use out of our PopUp. Made two 2400 mile trips, one 600 mile trip and a whole slew of short hauls with it. Only complaint other than the plastic wheel wells was when the wind blew the raised top wobbled a bit and transferred that movement into the bottom half. Tow vehicle: IH Scout II. PopUp was a StarCraft.
TT: Had our 23' TT for about 10 yrs. Purchased used. Only a couple minor issues: Needed to tighten the water connection in the bathroom one time and the tank level indicators never worked. Our only dislike was that the heater was located underneath the master bed. We had to keep it at a storage facility where it was broken into and the chipboard underfloor soaked from rain. Got a great deal on replacing the underfloor with marine ply and back in perfect condition again. Sold it when our new '99 F150 4x4 couldn't handle the mass. Our '86 F150 4x4 had no problem towing it though. Best part was 4-season comfort. In-use security increased considerably from PopUp. Oh, plus it had an oven we used for roasting game hens. Let me tell you that makes for one delicious meal!
Class C MH: Just purchased a used 2015 . We haven't taken possession of it yet. Wife didn't want us to be hitching up then packing up a TT anymore. Her new motto is, "Get in and go!" Very spacious inside for the 2 of us including the occasional grandchild. Plus it has an oven for roasting game hens! It seems ovens are being phased out in the newest MHs along with 3 & 4 burner stoves.
Miscellaneous: For the first few years we owned our TT we lived in a neighborhood with covenants. I would bring the TT home from storage on Thursday evenings to give us time to load it so we could take off right after work on Fridays. At first I unhooked the TT along the curb in front of our house. The CCR people called the law on me and I got several warning tickets.
The local law says 48 hours on the street max
so what I learned to do was leave the TT hitched up to my truck and the law would leave us alone. CCRs covered my property but not the street in front of it.
This made for a bit more stress getting to work Friday mornings but we managed.
Since then we've moved to a small acreage where there are "No Covenants!" Life is less stressful now.
