I am new to this site(newbe) so let er rip
Have 2000 Z71 5.3 tow pkg pure stock, last summer installed
5th wheel rails and 21' 5th wheel dual axle camper, loaded around
6k. Took several trips and performed in my opinion good. I am in central
Colo. and on tough climbs speed dropped to 35-45.
Now have a 17' i/o to tag along, professional hitch on trailer. Now I am
hitting 35 or less on tough climbs but on open road Colo. style can maintain
65 easy. Would like to increase HP I know in previous hook-up my mpg is
going to be 6-9. Just would like to have more ponies on tough climbs.
Oh just an add 140K and runs great empty.
