A double-sided trailer carries two screens on one mast, one chassis and one tow. For a roadside advertising position between two directions of traffic, that is not a marginal improvement, it is the difference between selling half the traffic and all of it. It is also the cheapest screen area in the MOBO line.
The cost case
The chassis, hydraulic mast, control system, wiring and bodywork cost roughly the same whether they carry one screen or two. Put a second face on the same mast and you pay close to the marginal cost of panels for a second audience. That shows up clearly when you compare cost per square foot across the line.
| Model | Configuration | Total screen | Starting price | Per sq ft |
|---|---|---|---|---|
| MB-5D | Two 9.84' x 4.92' faces | 97 sq ft | From $36,500 | About $375 |
| MB-5 Lite | Single 9.84' x 4.92' face | 48 sq ft | From $30,000 | About $625 |
| MB-7 Lite | Single 11.48' x 6.56' face | 75 sq ft | From $39,500 | About $525 |
| MB-10 | Single 13.12' x 8.2' face | 108 sq ft | From $55,000 | About $510 |
| MB-7D | Two 12.6' x 6.3' faces | 159 sq ft | Built to order | Quoted |
The MB-5D gives you roughly twice the screen area of the MB-5 Lite for $6,500 more. That is the strongest value proposition in the MOBO line on a pure square-footage basis. It is only the right buy if you have two audiences, though. Ninety-seven square feet split across two faces is not the same product as 97 square feet facing one crowd, and no amount of cost-per-foot arithmetic changes that.
Where two faces win
Every one of these has the same structure: two streams of viewers moving in opposite directions past a single spot you can legally park in.
Position 01
Parked between two directions of traffic, both faces work simultaneously from one position and one tow. This is the archetypal double-sided placement and the reason the configuration exists.
Position 02
A single position at a venue entrance catches arriving traffic on one face and departing traffic on the other, across the whole event window rather than just one half of it.
Position 03
Shopping centre and dealership frontage where pedestrians approach from the lot and vehicles pass on the street. Two different audiences, two different messages, one parking space.
Position 04
Two faces let two advertisers hold different directions at the same time, which changes what you can sell. Specify independent scheduling per face when you order if this is your model.
Position 05
Foot traffic circulating in both directions through a lot means a single face is dark to half of it at any moment. Two faces halve the number of positions you need to work.
Position 06
A trailer in a parade or moving a route is seen from both sides of the street. One face means half the spectators see the back of your trailer.
And the counter-case, stated plainly: for a festival stage, a movie night, a watch party or any single seated crowd, put all your pixels on one face. The MB-15 at 17 by 10 feet will serve that audience far better than two smaller screens, half of which nobody is looking at.
Before you sell a placement
The trailer is the straightforward part: US DOT compliant, VIN that decodes in the NHTSA system, DOT-approved lighting, tires and couplers, electric brakes, breakaway kit. It titles and registers like any commercial trailer anywhere in the country.
Where you may park it and display advertising is an entirely separate question answered by local law, and the answers are not consistent. A number of US cities and counties specifically regulate mobile billboard advertising. The provisions we see most often restrict vehicles parked primarily to display advertising, cap how long such a vehicle may stay in one position, require a permit, or regulate brightness and operating hours for illuminated signage. Some prohibit the practice outright.
The practical discipline is simple. Before you sell a client a position, read the sign ordinance for that jurisdiction, and if the language is ambiguous, call code enforcement and ask directly. Get written permission for private property and confirm it does not conflict with the property's own sign restrictions or lease terms. A campaign shut down on day two costs you the refund and the client.

A trailer with two LED screens mounted back to back on the same hydraulic mast, so the unit displays to two opposite directions at once from a single parking position. The MOBO MB-5D carries two 9.84 by 4.92 foot faces and starts at $36,500; the MB-7D carries two 12.6 by 6.3 foot faces and is built to order. Both deploy in about 10 to 15 minutes by one person with no tools.
For roadside advertising, the arithmetic is unusually clear. The MB-5D delivers 97 square feet of screen across two faces from $36,500, which works out to roughly $375 per square foot, the lowest in the MOBO line, because the chassis, mast, hydraulics and control system are shared between the two screens. If your positions have traffic in two directions, you are buying the second audience at close to the marginal cost of the panels.
Whenever you have one audience in one place. At a festival, a movie night, a stadium lot or a watch party, everyone is looking the same way, and a single 17 by 10 foot face on an MB-15 serves them far better than two 9.84 by 4.92 foot faces of which they can only see one. Double-sided is a roadside and route answer, not an event answer.
That depends on the configuration and the playback setup, and it is worth specifying explicitly when you order rather than assuming. Operators who sell shared loops often want independent scheduling per face so two advertisers can hold different directions simultaneously. Tell us how you intend to sell the screen and we will confirm what the configuration supports.
The trailer is DOT compliant and registers like any commercial trailer, but where you may park it to display advertising is governed by local sign ordinances, and those differ sharply between jurisdictions. Some cities restrict or prohibit vehicles parked primarily to display advertising, some cap duration in one position, some regulate brightness and hours for illuminated signs. Read the ordinance for every jurisdiction on your route before you sell a placement there. General information, not legal advice.
The MB-5D is in the smaller end of the line and the Lite and small Deluxe models are generally half-ton towable, but confirm the specific weight ratings with your quote against the truck you actually own before you commit. Getting the tow rating wrong is the most common and most expensive planning mistake in this category.
