Recreational & Family - Kid Kaboose trailer questions

I've been doing research and homework on kid trailers, trying to learn and find information on good designs, features, construction, etc. I found a kid trailer for a good price, though it needs a good cleaning and maybe a good tuning. I have not found any information on the actual trailer, a Kid Kaboose 2-seat model, on BikeForums or after Google seraches. If anyone can help me find more information and answer a few basic questions (or provide links to good answers/discussions), i would forever be greatly thankful.

Questions:
1. Has anyone even heard of "Kid Kaboose?" Is it any good, or an x-mart special? The one i found has spoked wheels, steel i'm assuming by the slight rust. I didn't get a real good look/examination, so i might not be able to provide the best answers on questions to me. I'll probably go look again this weekend.

2. Trailer hitch design: The trailer hitch arm attatches to the rear triangle with a clamp, with a tough wound spring to allow for flex. Without getting too specific and without pics to help, what style hitch works well? I'll most likely be using the trailer with a hardtail mountain bike.

3. Trailer wheels: How is wheel maintenance different with single sided wheels as opposed to regular bicycle wheels? Is there a greater amount of stress with most of the load being on one side of the wheel? Can the wheels even be removed from the trailer?

4. Comfort and use: Are trailers that comfortable? My daughter will be almost a year old next summer and i'd like to get more riding in. Is the usual padding/seating in kid's trailers comfortable for an hour or two of riding? Should i look into making padded seats with foam, pillows, blankets, etc.? Obviously it varies widely between trailers, so i'm just getting a consensus.

I'm obviously new to the entire kid's trailer concept, so any help is greatly appreciated. I'd mostly like to know if the trailer is just cheap junk that i shouldn't waste the money and garage space on, or if it would be decent enough to last a few summers with minimal repair/tuning. Thank you everyone in advance for your input.

I cant find information on that one but I have one that is simular to it. It has spring and clamp arm, removable wheels are critical for getting it in you car when traveling. It sounds like a kinda cheap one but how good does it need to be. Are going to use it for long trips? or daily? or just in the summer to go to the park? I have owned a burley D'lite single and a cheap double trailer I have now and I cant tell the difference while pulling it. Just make sure the closures are good and look like they would keep out rain if needed.
I personally use my trailer 4-5 times a week to take the kids and the dog to the park, store , beach and what ever else I can think of. I love my cheap trailer and might upgrade to a nicer one someday but I doubt it will be soon since ther really insnt anything to break.
As for the single sided wheels that doesnt seem to be an issue, I haul two kids and grocereys around and havent had any signs of wear on the hubs in two years.
The comfort issue- a blanket under small kids ( under 2) feet helps to keep them from sagging in thier seat. Some trailers have better harnesses and seats than others but my kids went from the best to a cheaper model and really didnt notice, even on 4 plus hour rides.
My Burley had a better mounting system than my cheap one ( spring and clamp) but other than taking an extra minute to hook up it hasnt been an issue.
Good luck

Thanks for the information!
I'm not planning on taking the trailer on any long trips, probably just local trails and to the park. The one i found is pretty inexpensive, so i might just give it a try. I'll post an update if i pick it up.
