I don't spend much time in my TT either. I'm just a weekend camper. I have a girlfriend that sometimes goes along. I have friends kids that sometimes go along. I have a 22 foot TT with no slide and I love it.
I want a shorter TT with a rear bath. I want my dinette to be on the curb side so when I have breakfast in the morning or the occasional rain storm I can set and look out at the campsite.
The only TT's they make like this have no slides. And, they don't make many of them. I sure love the one I have but, it's 24 years old and it doesn't have much life left in it.
I will try to squeeze a few more years out of that and then who knows. I may have to give up camping because I can't find a decent TT. Things can change in time though.
