Recommendations for a noob...

You bought the right truck for the camper. The first thing lots of folks get wrong. I've used Torquelift, chains, and turn buckles for as long as I've had my setup. One thing I did do was get stainless steel chain connectors. I bought BIG turnbuckles and they're aluminum. Get a good quality blue drinking water hose so you don't get so much plastic taste in your water connection. It's a Ford so getting power to the TC through your pigtail is available. My truck a cube relay was required to be installed next to the fuse panel under the hood. research how yours works. Also, one the best things to do is get a smart solenoid and connect a 4 gauge from your alternator to your TC batteries for much better charging. I would get at least a 300 watt solar system installed with an MPPT controller. You can go from there how you want with batteries and other improvements. A 1000 watt pure sine wave inverter is a great thing to have for running your 120 volt appliances. Paper Plates, plastic ware, baby wipes, a couple GOOD camp chairs, ziploc bags. You can build a pretty good list. I kind of concentrated on things for the truck and camper. For other stuff, just get what you like at home and see how it fits in for your travel style and before long, you'll have a good idea of what works. Best wishes on your soon to be travels...
