I've looked at droppers but couldn't find 40amp one if you know of such a dropper it would be my best bet if not we all know a truck has 2x12volt batts

Forget the voltage issue for a minute and focus on the 40 amps. That is an awesome amount of power which would need very heavy cabling. Not a good idea at all to try and take 40 amps from one battery in a 24 v system. Is there any chance you are trying to connect multiple 12v units which draw a total of 40 amps? If so you could link up pairs of units in series so they will each get their 12 v but you will then have to ensure that each unit is not earthed to chassis.

If you have 2 x 12 volt batteries then just connect across one of them. NB make sure it's the one with one end grounded to chassis. If it's a single battery does it have exposed connection bars on top? If it does you can tap off 12 volts easily.
NOTE You mention 40 amps. If you draw this sort of current for any time from half a battery system the other half will be badly overcharged as effectively the 40 amps will have to pass through the other battery while running

If it really does have 2* 12V batteries then just connect to ONE of the batteries. Voila. 12V

yes no problem just watch you don't drain 1 batt, if you do you will find that alt wont charge either batt

"Should be ok if taken from ONE of the two batteries" quoting my partner.

yes you can BUT It will probably not work due to insuficiant power supply
