Advice on buying a new travel trailer on a budget?

U and I RV in Logan is listing a KZ Sportsmen Classic 19BH for a hair under $13K. That is a bit too long for your requirements, but you could ask them about ordering you a 150BH (and it might be less money, since it's shorter). I had a 14RB for about 3 years and it was decent. None of the trailers at that price point are anything great quality-wise, but they are serviceable as long as you keep them maintained, including a roof inspection every year.
