One follow up question: for what I can find out, it looks like the engine size and transmission are the weak links. Would it help if I did some mods to help increase the HP and maybe a bit more drastic change to the gear ratio?
No on the engine mods - waste of money.
On the re-gearing, while it would improve towing performance I don't think it is a wise investment unless you plan to keep the truck a long time. It'll set you back about $800 per axle, so double that if your truck is a 4x4.
