Neoseeker is posting cheats and tips, so when The Solo MMO Player wanted to know how to carry more weight in his inventory, I found this posting by Machienzo.

Machienzo says, "This can only be done through the 'Command Mode'. By commanding your companion to 'Pick Up' stuff that you've left on the ground, you can tell them to pick up an unlimited number of items. It has to be through this way, otherwise they will end up being over-encumbered."
UPDATE: A video explaining how to use increase carry weight using the console commands
in the PC version of the game. You access the console command using the tilde key ~ on your PC keyboard. The Solo MMO Player tested this and it works (for now).
