Glad to hear you have the 3:42s. That would be a real bummer if you didn't.
Have you considered looking at hybrid trailers? Lots of room for a family, lots more floor space than a similarly sized TT, and far lighter in most cases. For example, the
Jayco X23F has 3 beds, a slideout dinette, and a GVWR of 5,995#, well within your XL's ratings and a tongue weight light enough to not eat your entire CCC in your XL. Granted hybrids aren't everyone's cup of tea, but lots of us love them. We had our first HTT for 10 years, and bought a new one last year. Just a thought...
