I would suggest a small low trailer. Lots of injuries from loading up onto high pickups. ,, Ramps kicking out. safety chains not being used etc. a small trailer,, super simple and safe. though a bit of a hassle turning around in tight places. You can build one pretty cheap if mechanically inclined and some welding skills. a twisted or pinched ankle or wrist is no fun and can put a end to the fun. I have seen a lot of mishaps loading and unloading. plus keeps the bed and rear window undamaged.
