You got the part about making the memories right! Take the kids everywhere you can, was my motto.
Really, most late model trucks are really good about fluids with little use. As long as it's parking space doesn't have big swings of temperature and humidity, you should do fine. I would just keep to a regular maintenance schedule with maybe a few tweaks. Your battery is one consideration, they always need maintenance and charging. If you're parking for more than a few weeks, the battery could be pulled and put on a charger at home. If the truck is going to sit over winter, a cover might be a good acquisition. Check tire pressures so they are maintained.
If you can exercise the truck every so often, there should be nothing more to do.
