I am looking at buying a travel trailer. I currently have a 2005 Chevy Suburban 1500 Z71. I don't know how much longer it will last as it is burning oil. I have been looking at used trucks but ...
Modern gas motors are going 150K+ without major problems. That does not mean everything else wont break. Realistically if your planning a tow vehicle there are plenty of low (under 50K miles) vehicles around. Places like ebay motors will give you a glimpse of whats available. Your in OH, so there is no reason not to start looking in VA or the Carolinas for clean rust free trucks. Depending on how many people you need to carry dont overlook Ford E250/350 passanger vans.
