See Table: Actions in Combat for other move actions. You can take a move action in place of a standard action. If you move no actual distance in a round (commonly because you have swapped your move action for one or more equivalent actions), you can take one 5-foot step either before, during, or after the action.
Buying a mobile office trailer is a major investment. A mobile office that costs $200 to $500 per month to rent could retail for $20,000 to $30,000. The cost of leasing that office for a year would be $3,600 to $4,500, not including delivery, setup and removal.
Trailers for personal watercraft start at $600-$800 for do-it-yourself kits for a lightweight single-axle trailer, and can cost $1,000-$2,800 or more depending on whether the trailer is single or tandem axle, if it's galvanized and whether it holds one to three personal watercraft.
