OP did not report back, but chances that batteries sitting dead whole winter will recharge are very slim.
That is why I automatically suggest removal from the truck.
Vehicles always draw some current when in park. On old cars/truck you had a clock, on newer one alarm and remote system. Different vehicles can sit longer time without recharging and when my sedans and new F350 will restart after 5 weeks, some luxury cars are reported to drain battery even in 3 days.
He said truck was sitting all winter, not the batteries were dead all winter. My 1+ year old batteries died during a 3+ week spell it rarely got out of the teens. Put the charger to them and they came right back.
Unless the OP knows the batteries are old or just wants the exercise, IMHO it makes sense to attempt a recharge in the truck.
