If I were choosing between just those two bikes, I'd go look at the Pack Rat and see if it fit but be ready to pass if it doesn't. The LHT is a bike I've only tried once and it was stable and hard and heavy. Perfect for heavy duty but I don't know if I'd want to zip around commuting on it. But I wouldn't get my heart set on either. If the link posted earlier is correct then the LHT might be gone. 2017-me was really interested in the Pack Rat but 2024-me wants to want to pop it over curbs and neither of these bikes with luggage mounted are going to be great at that
