Here is a pic of my Trumpeter M1A1 with Mineplow:

There are a number of things I changed out to make the kit better.
1. Fixed the turret face on the gunners/loaders side. YOu can get by without fixing it, but if you know the problem is there, is sticks out like a sore thumb.
2. The suspension is rather fragile, more so that either Tamiya or DML. I snapped off a raodwheel arm when attaching my tracks.
3. I attach my tracks last, THEN add the side skirts. Yes, it means a fair amount of temporary assembly to get the cammo done correctly, but I think it is worth the effort and it makes putting on the tracks infinately easier. I cannot even imagine putting tracks on with the sideskirts in place...yikes!
4. Also, when putting vinyl tracks together, I find it easiest to staple them in place, THEN use the hot-knife method to connect them, then just paint over the whole mess. The side skirts hide the staples anyhow.
5. Because of the nature of the Vinyl, paint is just going to peel off. The only way to really avoid this is to handle them as little as possible, period.
Hope this helps you keep on finishing the kit.
