No matter what sort of model trucks that you like to collect you will find that it can be fun and very interesting as well. Die cast ones that come pre-assembled can be fun but the plastic ones that you can build yourself can make a great hobby. It will be a hobby that you will be able to share with your children and your family as well. Another benefit comes in when you find out that you are able to stand back and admire the work that you have put into the model that you have been able to modify yourself.
A way to really add a great deal of detail to your model truck is to make working parts for it. You can created many different parts that work including headlights and tail lights that work all the way down to working doors, hoods, and tailgates. This can help to dress up a tuck so that it is much more interesting. One of the things you will need to consider will be the scale of the truck with which you are working. Too small of a scale will limit you as to exactly which changes you might be able to initiate. There are some changes that will not make very good matches for your project.
If you will want to make an opening tailgate for your truck then you should be able to handle it rather easily. All you will have to do is to take a sharp bladed hobby knife and carefully detach your tail gate from the rest of the truck bed. Try not to remove too much material when you do this. You will have to consider exactly how you wish to reattach the tailgate once you have it cut loose. You may have to use a paper clip to make a small joint for the tailgate to pivot on. You will just have to straighten it out and snip part off. You can then run this part through the tailgate and into the sides of the bed.
This will give you a good looking and functional tailgate. You can also use this paper clip trick to be able to create some hinges for your doors if you choose to make them work as well. Once again you will need to make sure to cut them out slowly and carefully. Another thing you will have to consider is whether you will add any more changes such as adding a spare tire to your new truck bed for looks or by throwing some painted up spare parts from other cars in the bed to look like you are transporting parts.
Another change you can make quite easily is working head and tail lights. For these you will first need to make sure that your model truck has come with light covers that are not opaque. You will first have to remove some material from the body where the lights will be mounted. Next you will be able to run some doll house lights from to each of the head and tail lights. You can then run your wires to the battery in one of two ways. You can either run them down the undercarriage and attach the battery there or else you can install it in the bed of the truck.. This can look poorly so you might want to consider the former choice first.
The listed adaptations are just a few of the ones that you can do to personalize your model truck. If you apply just a little bit of experimentation combined with some imagination as well you will be able to create some very innovative details for your model truck.
