There are a number of ways of doing this. All will require some preparation, but once you have done that preparation the next quote is going to be much more simple.
There are three issues that need to be addressed:
1. Your post states that you paste the specification and then include
several pictures. Later you say that you want two columns with the spec in one column and the picture (singular) in the other. That doesn't appear to compute.
Do you want one spec and several pictures or one spec and one picture alongside?
2. How much specification text is involved and do you have the pictures stored on file or only available from old quotes to copy and paste?
3. How many trucks are there to choose from?
The choices seem to be some sort of mail merge, or a custom application dedicated to the process. Both would require a data source that holds all the data about the trucks from which you can select the required items.
Take a look at
http://www.gmayor.com/photo_gallery_template.html which doesn't do what you want, but gives you an insight into what I had in mind with respect to picking items and inserting them into a table.
If you want to do it manually then use a two column table. Incidentally if you start with a page with a very wide left (or right) margin (leaving less than half the width of the page available) and set the aforementioned template to display the images 1 across. It will create a narrow single column table containing the images (loaded from disc). It is then a simple matter to reset the margin and add another column to the table for the descriptions.
