One of the joys of GURPS, in theory, is that you can run anything you can think of in it. One of the joys of running well-designed D&D modules, from AD&D's Against the Giants series to the best of OSR adventures today, is that they are different from stuff you write yourself. They can surprise you and teach you new things. There are some monsters that D&D and DFRPG share in common, like ogres, goblins, dragons, and mariliths/peshkalis, and there are products out there like Nordlond Bestiary which provide quite a lot of others, but what do you do about traps and treasure?
Here are my rules:
1.) For treasure values, divide gold piece amounts by 100 and silver amounts by 10, e.g. if the module says you find 200 gp and 35 silver, you find two gold pieces ($800) and three silver pieces ($60). For jewelry/trade goods/etc. apply this same rule directly to the value of the jewels/etc. using whatever currency the value is given in.
2.) For traps, if it's a known trap type from the DFRPG books like a deadfall or crossbow trap, use whatever is listed there. Otherwise, it's noticed with a Per check; Disarmed with a Traps check; unavoidable unless disarmed; and if it's triggered it is Saved/Evaded with a DX check (or Will check if magical, HT check if poisonous), and does the same damage as listed in the module. Since D&D and DFRPG use HP differently, traps with large damage amounts in D&D (e.g. 5d10 poison) are sometimes intended to be reliably lethal, but that's better represented in DFRPG by making them difficult to avoid. Every time you cut the damage dice in half, rounded up, add a -2 penalty to all detection/disarm/evasion rolls. For example, if an evil lich king's tomb has a poison gas damage trap that does 5d10 poison damage per round for 10 rounds if triggered, in DFRPG you can convert it to a 3d10 toxic damage per second gas trap that is detected by Per-2, disarmed by Traps-2, and does no damage this second if you succeed against HT-2. Or you can halve the damage twice more to get a 1d10 damage per second trap that's detected by Per-6, disarmed by Traps-6, and resisted by HT-6.
3.) In all cases, if these simple defaults feel off to you, tweak them! If you want to convert the gas trap from 1d10 damage to 2d6, detected at Per and disarmed at Traps-6 but with no HT check to avoid the damage, do so. These rules are just a starting point to save you hassle for things you don't have a strong opinion about.
Happy gaming to all!
