Bakerkids, fun to see those pics of Green Bay and Kohler-Andrae, one of our favorite parks. If you want to go next year, make reservations ASAP. Wisconsin takes reservations 11 months in advance, and you'll need them!
Hybrids are wonderful if you like to spend time in state/national parks & forests. They are great in nice weather. Like popups, they can be a bit damp in rainy weather, and they are a pain to set up completely in a pouring rain. (Anything is, but if you want to deploy the bed ends, you and the beds will get soaked.) If you are camping in a noisy spot - right by the interstate highway, for example, or in a crowded campground on a holiday weekend - you will get all the noise as if you were outside, since canvas absorbs very little sound. Should you choose to "turtle" and sleep on the couch/dinette instead, be aware that in most models, those alternatives are made for young children, and not full-size adults. (Been there, done that, exactly ONCE.)
If your kids have a minivan, they may have trouble pulling any but the smallest hybrids anyway. Just a thought. (We pulled ours with a 6-cyl older Explorer, and decided to avoid mountains entirely.)
Only you can decide what's best for you, but if it were my choice, for long periods of use, I'd go with a fully enclosed trailer.
Good luck with your decision!
We have the twin to skipnchar's and have had problems with wheel hubs & axles from the second year of ownership. We have towed ours about 30,000 miles (ballpark figure). We did visit the factory (a few years after we purchased ours) and were pretty impressed with how they are put together, especially for a lightweight unit, so I'm pretty sure we just got a lemon. Nevertheless, just FYI. Haven't seen the model you describe. Forest River IMO makes decent campers, but perhaps not the best consideration for very heavy usage. Very comfortable inside, and lots of little niceties that some other manufacturers don't think of - lights in the pass-thru storage compartment, heated mattress, space for a clothes hamper, stuff like that. Lots of storage space - too much, in fact, in ours, since it has a very low cargo capacity for its size.
One thing we found when we had our small C without a toad was that, if we needed anything (campfire wood, groceries, etc.) or wanted to go sightseeing, we had to unhook all the utilities, put away the leveling boards, go run our errands, then come back and set up camp all over again. That was pretty much of a pain. That, and in some CGs, especially national/state parks, unless you left something in your site, someone might come & take it while you're gone. (Didn't happen to us, but we did see it happen to others from time to time.) With a trailer, we didn't have that problem.
As others have said, it all depends on your camping style.
As someone on here once said about the Tundra, "more engine than truck." Having owned one for 7 years now, I fully agree. It's great for towing (as long as you stay within the weights) but since the rear of the truck has a lighter frame construction than the front, it's just not made for large payload. There are some very basic truck campers - more like tent campers that fit in a truck bed - that would work, but somehow I have a feeling you're not looking for that.
Considering the state has to pay to run the park (for however long they agreed), no wonder all they could reopen was GCNP. On the other hand, if you can afford only one, why not go for the flagship in the state?
As for not bothering, this is high season for the southern Utah parks, and a pretty popular time for Grand Canyon too. Weather there these days is just about perfect, not too hot for hiking, etc.
Our experience with our Flagstaff (twin to skipnchar's Rockwood) was not quite so positive. Probably a total of about 30K miles towing and we've had fairly frequent problems with wheel hubs, even to the point of replacing one axle. Other than that, we've really enjoyed the trailer - just a bit large for where we like to camp. We visited the Forest River trailer factory where they made our unit (we did this several years after buying our TT) and were pretty impressed with how they built them, especially considering their relatively light weight for the size.
Not the "best" of trailers, but respectable.
When we pulled into the Village of Trees RV Park in Declo, ID last month, we noticed a problem with one of our wheels. Noticed the CG had ads for 2 different mobile mechanics in their flyer, and called one of them, Rob's Mobile Repair Service. He came out to the CG that (Saturday) evening, had a look, and said he wanted to redo our wheel hubs. He pulled both axles, but the other axle he didn't feel needed work (it had been replaced a year ago, and we haven't gone very far this year). He was back Monday morning with the parts, replaced the bearings and we were ready to roll by noon. Excellent service, we feel. I'd make the trek there again just for that!
Mbopp's experience is similar to ours when we traded our PUP for a HTT. My main problems with the HTT were
1)that, like a PUP, I had to make the bed while sitting on it
2)the front bed end leaked a little when driven in the rain - with potential longterm damage
3) sleeping discomfort for adults when turtled
Loved the open feel with the tented bed ends, but the downside was less insulation from damp weather and from noise from other campers, compared with a fully-enclosed TT.
I can totally sympathize with the OP. Our TT is a Forest River product, and has Lippert axles and slideout mechanism. Haven't had any trouble with the slideout in the 6 seasons we've owned the trailer, but the wheels, hubs and axles have been the bane of our existence. Granted, we have put a lot of miles on the trailer, but on a recent, relatively short vacation (900 miles and 7 days total), we discovered grease leaking out around the grease cap on one wheel (again?!?!) when pulling into our first CG, 80 miles from home. The mobile mechanic the CG recommended (who, it seems, did an excellent job repacking bearings on two wheels) told us several times that he sees this problem a lot - and the main reason, he feels, is that bearing jobs are considered to be "grunt work" and many, if not most, RV repair shops let the least experienced guy do them. As a result, hubs might be too tight or too loose, bearings not changed when they should have been, the wrong kind/amount of grease applied, etc. I think this happened to us, though the first hub blowout we had, when the TT was only a year old, may be a result of original equipment failure or improper bearing job done at the factory. We'll never know. We have had one axle replaced and one spindle on the other one replaced. This last time, the problem hub had been put on too tight, and its companion (opposite side of the trailer) too loose, causing uneven tire wear. Needless to say, we are pretty gunshy about trailer wheels now.
We have had accumulators in our HTT and our TT - in fact, we added it to the second rig because we liked how it reduced the use of the pump motor. (Basically, if you're using the water pump for any length of time, rather than running constantly, having an accumulator will make it pulse instead.) Will probably get an accumulator in our next unit.
