Not buying a dually suburban when I had the chance. I came across a 4x4 dually suburban with lockers front and rear a 454 and a small lift that was in great shape for something like $5000. It had previously been used for a search and rescue vehicle. I was kind of looking for a vehicle at the time but wasn’t necessarily serious. I was talked out of it because I didn’t need a large truck and it would have drank fuel like it was going out of style. But, I regret that now. I wish I had bought it, it was an awesome.
Below is an example of one.
