With very little work it could be made to look like a Volvo conventional (N Cab) Tank Transporter and there is space under the Bonnet for an IBU2 (truck) control board all for less than £80 less control board and servos. there are, excuse me, truck loads of accessories available for 1/16 Bruder trucks including lights and other detailing and much cheaper than Tamiya's similar products.
There are other 1/16 tractor units in the Bruder range such as Scania and MAN but these are Cab over/Tilt cabs which would need work to convert to Conventional's.
It has to be better value than TAMIYAS overpriced 1/14 scale trucks and separately overpriced 1/14 trailers for hauling an ABRAMS, CHALLENGER 2 or a LEOPARD and it is at the correct scale.
