I've been towing my current trailer with my Sienna for a 5 years now. It works great. The Odyssey should perform similarly. You do have to watch your weight, but you don't have to limit yourself to trailers with a GVWR of 3500 lbs. (Mine has a GVWR of 5600 lbs.) What's important is what it actually weighs when you're fully loaded and ready to go. (For me, that's about 3200 lbs.) In order to keep the weight down I don't carry water or food. I get those at my destination. I also tow at 60 mph, but you'll find a lot of people here recommend that regardless.
There are several other people on this forum who also tow with minivans.
Biking: Cuyahoga Valley
Hiking: Hocking Hills
Both have both, though. Hocking Hills is a lot hillier, and more scenic. There are many trails that are accessible for kids (Ash Cave, Old Man's Cave, Conkles Hollow, various others). All in all, there's some great hiking. That same hilliness doesn't lend itself to good bicycling though, especially for kids. Cuyahoga Valley is more tame, has a really nice bike path, good hiking (although less scenic), and has more other attractions like the scenic railroad, and some nice small towns.
There's A LOT more camping in Hocking Hills (various state parks - the primary of which is Old Man's Cave campground at Hocking Hills SP, but there are others, as well as state forest and National Forest campgrounds). The only camping I know of at Cuyahoga Valley is for backpackers/overnight-bikers - not car camping - there's one small campground mainly setup for backpackers. There's also Portage Lakes SP just south of Akron, but it's not all that great.
For an interesting place to stay in Akron (not camping), check out the Quaker Square Inn.
The problem with the testing report provided by users of forums like this is that by and large you only get the negative reports. You don't hear anything from all the people that had no problems with a particular tire. This leads to a negative bias against popular brands - which may not fail frequently as a percentage, but appear to because there are so many of them in use.
Let's just assume for a minute that, on average, all tires are subjected to the same amount of good/bad care and therefore we can ignore things like over-loading, going too fast, under-inflation, road hazards, and so forth. (IMO, this is not something that we can assume, but let's do it anyway just to see what we can learn.)
Based on the information you've gleaned from forums, for each of the following please provide the failure rate as a percentage of the sample size, and the size of the sample (so that statistical significance can be calculated):
LT tires (of various brands)
Maxxis (Bias play and radial)
TowMax (and related brands) (Bias ply and radial)
Greenball (and related brands) (Bias ply and radial)
(add in other brands, as appropriate)
This sort of thing CAN and IS done with independent testing for other products. Not ST tires, unfortunately, though.
Consumer Reports gathers data from MANY people about the reliability of various cars, appliances, and the like. While anecdotal in nature, it includes both positive and negative reports (unlike the forums) and they get enough of it from their members to establish statistical significance. They don't report data for a particular model if they don't get enough responses for it to be statistically significant. They also do their own independent testing of these things, buying a number of samples from local retailers. They're funded by their members, not advertisers or other entities with an interest. Their reporting isn't perfect, but tends to be more accurate and useful than other sources.
They don't really do this for tires (they just test traction and handling, not reliability) and not at all for trailer tires. Either they or someone else could though, using the same model.
Actually, no. It's not.
There are (at least) a couple of things that you need in order for the aggregate anecdotal information provided in forums like this (and others) to be useful:
1. The total number of tires of a particular brand (model, size, etc.) in service on all of the trailers (or other vehicles) of all members of the sites where failures are reported, along with the total number of failures reported. This is needed so that you can calculate a rough percentage failure rate, and determine whether or not there is enough data about a given brand (model, etc...) to be statistically significant.
2. The exact conditions under which the tire was used, and the exact conditions under which the tire failed. For each tire, this would need to include the age from manufacture, the number of service miles, the pressure at time of failure, the lowest and highest pressures at which the tire was ever used, the average pressure at which the tire was used, the weight being supported by the specific tire (not the weight of the trailer divided by 4) at the time of failure, the lowest and highest weights the tire was ever subjected to, and the average weight the tire was subjected to. There are probably a handful of other things too (temperature, road conditions, for instance).
Without these crucial pieces of information there is no way to know that a particular tire is better or worse than any other. It could just be, for instance, that the sort of people that buy cheap tires (or keep the OEM tires, which tend to be cheap) also tend to be the sort of people that don't weigh their trailer, don't load carefully, don't tow level, exceed the speed rating, and don't check their pressure. Whereas the sort of folk that are concerned enough to buy a particular brand of tire with a better reputation could be the sort of folk that do take care to insure they operate well within the tires' limits (or who have learned to do so).
I also wouldn't be surprised if some portion of the reported failures are actually caused by road hazards (punctures) - this isn't always obvious after a tire's been destroyed.
It could also be that a particular brand really is better. From the information provided on sites like this, even in aggregate, there is just no way to know which of these (or other possible scenarios) is really the case.
There's no substitute for scientifically rigorous independent testing.
How many Volvos have you seen sitting on the side of the road waiting for the two truck? How many Chevy's? Can you thus conclude that Chevys are junk and should be avoided at all cost? Of course not! There are simply far more of them on the road, so the probability of seeing one broken down is much greater.
The same COULD be true for Maxxis tires. There are simply far fewer of them in use than there are of the other brands. (Without independent testing, we only have the anecdotes on here and will never really know if they're actually more or less reliable.)
My trailer rolled on OEM chinese bias ply tires for 5 years, until they wore out. I replaced them this past summer with chinese radials. I do like the radials better, but not so much that I would ditch the new tires that come with a trailer.
In terms of brands - I'm firmly of the opinion that if the weight on EACH TIRE is under the tires' rating (yes, this does vary depending on how the weight of the trailer is distributed and how level the trailer is front-to-back while being towed), and your speed is below the max speed rating of the tires, and you keep the tires properly inflated, and you don't run over something that punctures them, they're not likely to fail regardless of brand.
IMO, spinning off Lands End would be a good move. I didn't notice a change in Lands End quality when Sears bought them, but have since KMart bought Sears. LL Bean is now getting more of my business. Hopefully if they spin off Lands End, it can return to its former level of quality.
In terms of Sears, it is indeed sad. As with others, my first CC was a Sears card. I have relatives that worked most of their lives at Sears. My house is filled with Kenmore appliances. My toolbox is filled with Craftsman tools (especially the sockets and socket wrenches, adjustable wrenches, and the like - never cared for their power tools though). I used to always buy tires at Sears Auto Centers, but stopped after discovering they're now woefully under-staffed. My trailer uses DieHard GC2 6V batteries, now 5 years old and still going strong.
IMO, the Sears-KMart merger was a really bad move.
Having read the other threads, it seems quite likely to me the sources are actual users of the hitch. However, what's not clear is how many of these users tried to get 100% FALR. There are several people in the other threads that admit that they don't try to achieve that because they don't need/want to. That doesn't mean they couldn't. It also doesn't mean that they could. It's inconclusive. Unfortunately, there's no independent test agency for hitches, which is really a shame.
