Shortening BWS tilt deck trailer

Have a BWS air tilt tag with ramps that I want to shorten between 4'-6' in length as it's just a bear getting around in tight residential areas with a 42' OAL tag trailer, and I don't use the whole deck anyway. Being that it's a tilt deck I figure best way is cutting off the front apron, then cut frame etc and reweld apron, only other welding would be for the tilt hinge, air bag mounts and chain limiters.

What i'm trying to figure out is how short I should make it. I have 28' deck 6' beavertail now, BWS goes up to 4' shorter. I will measure but I believe right now hoe is about 7' from front, I would be ok with loading it right to the front after cutting and making trailer as short as possible. I also considered would it be wise to shorten the tongue? It seems excessively long at 7', is there some reason it's better to keep it so long?

When I was looking up axle spread to make sure I wouldn't get too short there (cutting 6' off would still be good that way) I realized the trailer is over legal length, it's 41' here so 1' over. Never had a problem but who knows if one day that could change so it's another reason I would like to shorten it.

Here is the trailer I have. There is not much that connects the trailer to the tongue so I can't see it being that bad to do other then making sure the two parts are lined up and the hinge is welded really well?

Went ahead with it and it's all done went 6' shorter will be so much nicer getting around. But holy crap it was WAY more work then I expected it to be. At least I know the trailer is well built, every single nook and cranny was completely welded, there was only 1 thing that was stitch welded. The front apron was welded on so well you could pull 100 ton on it without it budging.

In hindsight considering the time into it, probably would have made more sense to sell it and buy a shorter one, but I know the history of my trailer and how good of shape it's in and no dealing with people trying to sell something that is always a nightmare. Probably got 50 hours into it myself, plus about 12 hours of welder welding it back together for me.
