locked differentials

[Lmackattack]

Bob tail, no...loaded, slightly.

But a lot of this has to do with the stock 5th wheel mounting location. I have seen many tamiya kits have the 5th wheel centered over the tandems or moved rearward to give the truck,trailer a longer appearance.

1:1 trucks often run with the 5th wheel 9" ahead of center. This puts more weight up front and also aids you when backing as you can cut harder.

I run my rear rear locked for better climbing ability, and put real thick grease in the forward diff. I can drive thru grass with a load on no problem and in my opinion it's one of the best mods I have done to my trucks..
