I have a LHT and the bike is a tank. It's not fast but it's steady and load it up or pull a trailer and it really starts to shine. I can ride it comfortably all day long day after day it really starts to shine when you are three or four days out and doing 60-80 miles a day.
I do have a CF road bike and a zippy steel fixed-gear for when I am not lugging stuff around and riding all day day after day. Lugging and the long haul are what it is good at and I love my LHT for what it does well.
If I were you I would get another bike for when I was not doing those things.
