The crews met over dinner last night and today plan to head for the hills in the Lindis Pass to prove the mostly 1942-era jeeps are much more than museum pieces.
"We put the jeeps through their paces," Mr Reynolds said.
"Not in a vicious way, in a sedate way," Mr Reynolds explained.
For many of the sturdy workhorses it will be a return to former pastures as before they became collectors' items, they were utilised as farm trucks, he added.
Mr Reynolds restored his 1942 Willys jeep in 1996.
His son Earl helped organise this weekend's rally and the reasons the pair enjoy their jeep are two-fold.
"They are fun little vehicles to drive and . . . a marvellous piece of history," Mr Reynolds said.
