Backup truck, just in case.

I do remember my insurance company insisted both trucks be fully insured all the time, IF they were owned by the same entity that held the policy. I got around that by having policy under my company name and the second truck titled with my personal name. That way when I put it on the road I could add it and removed as the situation demanded. I also had a second trailer. If I had a load that had to sit I would just use the second.

 

There's still lots of nice pre emissions trucks around. Just have to be willing to take a road trip here or there. As far as your original question goes, having a second truck around isn't a bad idea. At some point I would like to find an older Marmon to restore as a toy/back up truck. The important thing is not to let them sit, especially if parked outside. That goes for any vehicle. I have an F350 that I use for occasional errands and to pull my skidsteer around. I always make it a point to drive it after it rains to shake the water out.

 

Cat motors are good motors if you get pre emission ones. Truck wise, just start searching now and you'll find something close.
