Bob,
I don't think you are looking for something that does not exist. I have a 1999 Nash 22H that I have had for the last 16 years. I bought this trailer because it was well-built, had great ground clearance and had a really nice frame under it. I have not been disappointed. This trailer has been hauled to Alaska, Key West, the East coast twice and to more remote Forest Service campgrounds than I can remember. It has a dinette, couch and other features you are looking for. I did not want a slide and have never missed owning one. It has a 15,000 btu AC on it, but I tend to not go camping where it is hot anyway. Coming from Tucson I am usually looking to escape the heat. I have added a shock kit, swapped out the charger to a smart charger and converted the batteries to 2 6V golf cart batteries. I pull it with a Ford Super Duty with a V-10, so have no issues there. I am not as familiar with the new Northwoods products, but would encourage you to go look at the Nash that you really like. I will refrain from deciding whether your current TV is enough truck to handle the Nash. In summation, my Nash has been one of the best purchases I have ever made. Yes, it is probably a bit heavy compared to other rigs, but crawl underneath and one would see why. A very tough durable trailer.
