If you use the P-Valve then you will want to put the condom catheter on in the privacy of your home. The tip of the catheter can be discreetly attached to the hose in the dry suit with reasonable care on your part.
even better you can rig up a long hose (does this make your cath DIR?) and stick it out the window of the truck on your drive home.
