I use my Raptor for the same purpose and it's been perfect. Carries everything we need, super comfortable, and fun to drive/explore wherever we land.
I have a nice tonneau cover and everything goes into specific water resistant crates. Not really necessary, but extra protection and helps the pack/unpack. Measured it out so everyone has their own, I have one for my work setup (multiple monitors, etc.), and another for random family stuff. Also carry bikes most the time with a hitch mounted Thule rack.
One long trip we needed to bring more and I ended up just lashing three extra crates on top of the tonneau cover. Wasn't perfect for security when stopping at hotels, but was fine for that one trip. If we needed more space, I'd do the RSI Smartcap, but would rather just limit what we bring. Makes the whole trip easier.
