Awhile ago our company did this for awhile but had problems with it...if We had a truck driver at the station we would put that on the road first if it was our box and full assignment,the idea was the truck can position itself where it needs to be positioned the engine behind will hit hydrant go inside and all that...Seems simple right? NOT! sometimes the engine was still a good x minutes out,or there was an engine crew(mutual aid usually) that did its own thing.Our truck is a quint so to speak 105 ft ariel ladder,7 ground ladders ranging up to 35,2 roof ladders,pump,500 gallons of water,and hose 5 in,1 3/4 inch,and 3 inch,but was wanted to be run as a truck only so there were those problems as well. We took it out first for automatic alarms as well. We are back to run engine out first. Now if we had a crew for engine and truck i wouldn't mind truck out first for that reason but one crew should be engine what does your department do and would you agree if the truck is first out?
