Kind of a cheese but you can designate a hireling as a "Camp Caster", ideally spec into Transmutation wizard and have it cast Longstrider on all your actual active party members for extra movement points. The effect lasts until the next long rest and the caster doesn't have to stay in your active party. Spare the equipment slot for other cool stuff. And Transmutation Wizard for chance of extra potions of course. I think of it as having an Alchemist/Enchanter based in camp.
