One thing for Texans to keep in mind - if you are running preserved military registration, you may NOT use the truck to carry your personal stuff around legally, unless you are going to a show and the gear is part of the show.
An example - a guy nearby got stopped recently driving down the road with a large white refrigerator, which he was moving for a friend, in the back of his M35. The deputy who stopped him was well aware of the HMV law, and was well aware that moving a refrigerator wasn't in compliance, so a citation was issued (operating outside of registration class), and justifiably so.
So, if you use your truck to move house and get caught......
Likely if you have collector insurance, and are using your MV as a regular truck, they could find grounds to deny coverage if you are involved in a collision.
To avoid this you can buy a 'trip ticket', which is a temporary permit to operate as a regular vehicle. They are for operating unregistered vehicles, or outside the normal registration class, and there are several types. I have used them numerous times, the last time I did so they were $5 for a one-way trip, and $15 for a permit good for several days. A LOT cheaper than a citation!
Check with your insurance company to see if you are covered, you may have to buy temporary supplemental coverage for the trip. Again, cheaper than having a claim denied.
