[RC] truck RPMs - Spottedracer

I'm no mechanic, but here's my experiences:

GMC 1/2 ton - pulling a 16' gooseneck horse trailer - PACKED with 5 horses. 
(nice having short horses)... Stayed around 2.5-3 RPMs until we hit the 
mountains... Shot up close to the red (think that's around 6), and we slowly 
lost speed until the top... Yep, truck WAS struggling to get up that mountain!

Dodge 2500 Diesel - heavy duty custom ordered for pulling.....Pull a 24+" 5 
horse slant, gooseneck steel trailer (Trailer's half the weight of equivalent 
aluminum)... Fully loaded with five heavy horses.. (Approx. 11-12,000 lbs)... 
Stays at 2-3 RPM.. In the mountain climbs (6% or steeper) - it'll drop down to 
low gear and RPMs shoot to right under red (approx 6 or so).. Truck loses 
velocity slowly... Yep, it's struggling!

So the higher the RPM - the harder the engine and transmission is working. 
Proper working range is from 1.5-3 (little cars or nothing on your truck - it 
should be around 1.5)  If you go into the red to long - something's going to 
blow.. (you should see what my friend ends up having to tow....)
