None of the above is good for slow climb.....
Find a TXT or Chod Buster if you want to craw........ or TLT if budget is not allowed.... (but to make a TLT to become a good crawler, you'll spend a ton of $$$ for modifications....)
i just can say, both u list item can't play slow climbing
for midnight pumpkin & blackfoot xtreme, it should be 2WD
and racing truck F150 using TA02 chassis which TA02 as a touring chassis.........
so both of it are not suitable for slow climbing
if u want to play slow climbing, there some u can choose which still available in stocks
TXT-1 (1/10)
Super Clod Buster (1/10)
TLT-1 (1/18)
F-350 (1/10)
for fun, u can choice wild willy 2, lunchbox or pumpkin
for more power for speed, blackfoot xtreme(2WD) or Twin Detonator(twins motor 4WD)
for look like more real, must be F350
