EW, please.
It's already in the Angler. Perfectly.
Please don't change it. Just give us the option to paint it and the atvs.
Make the atv a lot quieter, don't change the spook radius, and let us have access to the storage in the back of the jeep/atv.
It doesn't need to be a mobile store, it just needs to carry at least 2 people and add a new travel option that doesn't cause constant migraines.
All we need is the jeep, the storage in the back of the atv/jeep, and make the atv quieter (you literally don't need to change anything else about it but turn the volume down)
EDIT: Yes, I would happily pay for this. Standard dlc price would be MORE THAN WORTH what this would add
