I've read where some truck campers specify the ratio of gearing in the differential of their trucks used for truck camping. Would anyone out there be so kind so as to explain to me what the advantages...
When I was moving to different state, my combo was in the range of 18,000 lb as well. That was when I got pi** ed when I notice that my 3.55 differential allows the engine take 6% long grades without dropping from overdrive. What's the purpose of automatic transmission, when you drive 300 miles on single gear?
