Great option if you want to be legal....and follow all the laws....but if you happen to not be following the laws all this will do is draw attention to yourself which in turn will get you pulled over and inspected to see if you are following the laws. I'm not swaying you either way, just sayin. If you do add them maybe make them hidden, or have the strobes have a clear lens with amber bulbs, etc.....something...

I personally like the "trailer bridging".
It kind of reminds me of a trailer park or should I say "mobile home park", you have trailers with skirting and trailers without.
The ones with look much better.

The spare tire mounts on a trailer is a waste to me. My in town towing (8mi round trip) I don't even carry a spare. My 7hr trip to LOTO I carry 2 spares in truck bed. It makes no sense for me to mount tires to trailer, reach destination take tires off trailer put in truck or some place for safe storage, mount tires back on trailer for trip home, take tires off trailer put back in garage. Now days I would never leave my spare tires on trailer unattended.

1) Motorcycle cable lock.
2) Locking lug nuts on the studs holding the spare on.

Even with a Longbed, bed space is at a premium for me, as I always carry a full set of hand tools, 18V cordless impacts, drill, flashlights, spare parts, air lines; then luggage, and coolers. And on one trip, I had the Harley in the back too. (Hauled the AT down to Cape Coral for the owners' Thunder Run, and stopped at Daytona Bike week on the way down.) I'll never buy another Shortbed.

I also had twin tool boxes on my Myco too. All of my 2x6s for raising tires to changes flats where in one side, plus a grease gun on top.
On the left side of the trailer, were all my spare trailer parts (brakes, bearings, spindle), wipe down materials, brake fluid, spare oil for truck and boat, hitch accessories, shorepower pigtail, a bottle jack, road triangles, spare drain plugs, and a few other items. The more static items that I took with me every trip that could stay permanently in the trailer boxes..
...the better.

You don't need a strobe light to be legal unless you are 12' wide & 14' tall, then you will need an escort. At least in Iowa, Nebraska & Wyoming

You can lock your spare tires up all you want but that doesn't mean people still won't mess with them. IE, let air out or pull out Schrader valve. What really pisses me off is when they take your chrome caps.
If you need extra storage for coolers & luggage there will be a 40' trailer following pretty close.
I didn't say my routine will work for everyone but it works for me & not everyone takes their house on vacation.

they built mine also and its awesome

Beautiful boat, love the colors.

I don't care for the "trailer bridging" on the bottom side.

Trust me, you don't have to tell me about having your rig messed with.
I had my truck and trailer vandalized while we were all on a Poker Run, and it was a participant that did it.

You could save a ton of weight by carrying this little thing they call a MasterCard. Hell, you'd save so much capacity you could probably handle everything with a Tundra!

Oh trust me, I go through at least one Amex card every six months. They are worn as flat as my business cards by the time I am done. Now I know why they give out titanium black cards.

But the number of times I've been able to say "hang on a sec" when a friend or fellow boater needs something...
...makes it worth it.

I was helping a buddy change a ***** to get to starter last year before a charity event, and by the time we were done he was convinced I had valve spring and piston ring compressor tools in the back of my truck; and was considering doing a refresh then and there.
