Im going to replace USAR with a similar functioning unit possibly. As for engines, not sure what you mean. The set up will still be 2 ALS Engine, 2 BLS Engine, and 1 Tiller @ FS1 and 1 ALS Engine and 1 Tower Ladder @ FS2. The ALS @ FS 2 just wont be the 2003 Pierce Arrow that is commonly known as the ALS truck in the LA Mod. Just looking for some variety. I was hopping to have this released by now, pending Hoppah's permission of course, but my PC has been out of commission for the past 48 hours. However, JoseOu has given me permission to use his Dodge Charger EMS Car, C.F.D has given me permission to utilize parts of PRL, and ShaneGreen who inspired this sub mod based on his work on the SG Submod. Not to mention his patience and willingness to not teach me when I do thing wrong. Of course this wouldnt be possible with out the great work of Hoppah to begin with. I hope to have this released in the next 3 days pending some script changes I still need to do, and some beta testing. I already have beta testers in mind and some have been contacted.
