When I was stationed in England during my military years, I rented a house for few months with a wood fired oven in the small back yard. It was more along the bread oven lines, but you could heat it way up to do the flat breads stuck on the walls type cooking I got hooked on in the middle east. It also did great high heat thin crust pizzas as well. but took about 3 hours to get ready for that type cooking and burned a fair amount of wood in the process. Once heated you could have cooked pizzas for the whole neighborhood without going through much more wood than for a single pizza though as it retained heat well once up to temp.
While not capable of quite the high heat of a true pizza oven, what I now use is a pellet grill. I have a nice collection of stones I use in it and get a great wood fired flavor on the sorts of pizzas with thicker crusts that you want to cook at lower temps of say 400 to 500 degrees. Unlike my relatively inexpensive Camp Chef, some of the higher end units will get up well over 600 degrees F. On the plus side it throttles down to a smoky 180 or so which is perfect for absolute first class traditional bbq so the tradeoff is well worth it to me.
Definitely looks like a manufacturing defect that resulted in the metal becoming brittle. I've beat my equalizer hitch up pretty hard over the years, and it's held up really well other than wear and tear on the hardware, especially the L pins that hold the bars onto the L brackets on the trailer itself.
I have a 2012 Timber Ridge 240rks that I'm using for a third year now. It's not nearly as well assembled as the Springdale TT I had before it, seems they didn't drive a single screw straight, but I'd have to say most of the components are of better quality. I've drug it around about 16k miles so far and the screws have all fallen out of the cabinets a couple times and I've had to glue them back in. The plastic trim around the steps has weather cracked and is falling off already, and the awning track is pulling off the trailer. I've also had to rework a bunch of the trim around the bottom, mostly due to assembly issues and I've got some cracking on the corners of the front fiberglass cap that I'm keeping an eye on and may have to start doing repairs on shortly. Just about everything that has a connector in it plumbing wise has leaked at one point or other, as is common for TT's the tank quantity indicators are virtually worthless, and the floor is prone to being somewhat noisy.
On the plus side the layout is nice, and the TT does well insulation wise in the colder shoulder seasons when the nights get well below freezing. I've had issues during this time of year with my other RV's that I haven't experienced yet with the Timber Ridge.
How does it feel when you're towing? I put as much if not more faith in the how I find the setup to handle than I do in manufactures ratings or opinions of others. I towed a very similar TT behind a 2000 dodge Dakota which has a similar weight and wheelbase. I ended up covering around 15 thousand miles in the mountain west, driving on many of the roads you hear people being concerned about on these forums. The combo always felt good and handled well even on the mountain passes in the snow. That said, it always felt like I was pushing the drivetrain too hard, and the transmission did start to go out so I sold the truck, leading to a new diesel, resulting in too much truck for the trailer, thus a new TT. It can be expensive to upgrade the truck.
If the handling and braking are good, and you're inside the manufacture specs for towing I'd have no concerns.
It's interesting how different folks view camping, and how the progression often works. Myself, I still prefer tent camping backpacking style, but age, and the wifes hip make that a poor option for us most of the time. For national parks etc. I had a tent trailer, then went up to a class A which I found I didn't really like. In the sorts of areas I could take it, it seemed more easier to just motel camp. Next came a 19ft travel trailer, which could get in to most places, but the wife thought it cramped so we stepped up to a 25 foot TT. For the most part, we only use it for Forest service sorts of camping, and find we end up finding motel camping more to our liking for hitting the city sorts of trips.
