The LHT is very comfortable and stable, loaded or unloaded.
The photo with panniers shows the bike bagged out on an extended credit card tour. It's carrying about 35 lbs, including bags. Those are Arkel T-42 panniers on a Topeak MTX rack on back and Arkel GT-18 panniers on an AC LowRider rack up front.
The photo without panniers shows the bike configured for local or day rides, with a Topeak trunk bag.
