New to site but not rving but need some advice, We will be heading from Amarillo to Colorado Springs with a 34' Cedar Creek pulled by a 2001 Ford SuperDuty diesel automatic. But old Red has 212,000 miles on him so I'm concerned about any hard passes such as Raton that might be too hard for him(and ME). Appreciate any help anyone that has pulled this direction could provide. And do have a new tranny(stock) already on it with 4" exhaust,AFE air intake and Edge programmer.
