Tamiya King Hauler with stretched wheelbase
The Tamiya King Hauler is a nice truck model ,
but it just doesn't look right with that fairly short wheelbase
in relation to the position of the sleeper behind the cab
plus , the 5th wheel is to far in the back
( which is needed in stock form , otherwise there is not enough room for the stock Tamiya trailers )
there are several builders which either stretch the frame by cutting the frame-rails and inserting extensions ,
or manufacturing completely new frame-rails
for the new-comers to this hobby , that is maybe a little bit to much ,
since not everybody has the options to do these kind of modifications
here now a few fairly simple options to get this " longer wheelbase look "
the first option
is done without even drilling any new holes in the existing frame-rails !
and it can be done to a model which is already build
this first option will give you a 3/4" ( 19mm ) longer wheelbase !
and at the same time the position of the 5th wheel to the rear-axles moves in to a more realistic position
( even thought the 5th wheel stays in it's original location , since just the rear axles are being moved backwards )
this was accomplished by moving the rear-axle carrier 1 hole backwards .
shocks were also relocated in to existing frame holes
and the front fenders are mounted with spacers ( so I didn't had to drill the holes for the small pins )
( by a stock build King Hauler you would have to cut the upper portion of these fenders ,
otherwise your trailer will hang up , since they are positioned in that new location a little higher )
of course you will also need a longer drive shaft ,
but I will cover this separately at the end , since there are also various options for that
and since I never liked the straight cut end of the frame ,
I installed the slanted extension from a Tamiya Aeromax
the rear extensions from the Knight Hauler would work too .
In fact , I gone install the Knight Hauler tail-lights , since I like them better as the square ones from the Aeromax
now to option 2
this will give you a 1+1/4" ( 32mm ) longer wheelbase ,
but it does require drilling a few holes in the existing frame-rails ,
to move the axle-carrier further back
you will gain here an additional 1/2" ( 13mm ) over the option 1
option 3 is based on option 2
but requires a little more modeling skills ,
since here you would make the sleeper a little shorter
drive-shaft options will follow
