We FT'd for 7 yrs.
I was too busy enjoying the travel/adventure for any extra hobbies.
Besides as a FTvr we just didn't have the extra room for stuff. We sold everything an outfitted rig with want we needed.......then still got rid of stuff.
Now that we are off the road FT I am setting up my shop. Just wasn't something I found was needed when traveling....too busy :B
BUT it can be done........consider a 'tow hauler' garage could easily set up as a mobile shop. Just need proper tow vehicle.
Good luck on your adventure.
