A LHT will safely haul more weight than any tourist should sensibly ever attempt to carry for a long distance. If you haven't broken the rear wheel or frame of the Felt then you should be OK on a LHT with perhaps 50 lbs, although you should carry as little as necessary.
Calculate gear inches as follows: Calculate ratio of chainring to cog multiplied by approximate wheel diameter in inches. Example - LHT Complete is equipped with a 26/36/48T(tooth) crankset and a 11-32T cassette. For the 26" wheeled LHT, the low end gearing is 26/32*26= 21 gear inches. Likewise high end is 48/11*26=113 g.i. (which is unimportant to most tourists). Most tourists aim for <20 GI for loaded mountain travel.
If you get a LHT, get the 26" wheeled version if you don't need a frame larger than 58cm. The 700c wheels will not make you any faster when you're going down the road with a load and the aerodynamic profile of a Winnebago RV.
