The video shows the tow vehicle "scooping" toward and away from the parking space, while the diagram shows the vehicle driving past the space perpendicular to it. Also, the video shows no "critical" turn forward to the left.
I spent a lot of time researching backing up a trailer online, perhaps because I initially lacked any skills and my first tries were such abject failures. I learned about trailer pivot points from the web, as well as strategies for using mirrors and spotters. While I am certainly not an expert at it, I am much, much better. We went camping last weekend I got Ollie straight in the center both at the campsite and at the storage facility, both on the first try.
One variable is how wide the campground road is. If the road is very narrow, you may not have enough room to get the trailer angle positioned optimally when using the video swoop. In contrast the red-blue arrow version of the swoop can be done in a narrower space. Of course if the road is wide enough you have room to pull far enough forward to straighten out the trailer, as John put it.
To reverse, you crank the wheel hard back to the right while stationary (you do not want to waste any distance doing that while moving), then proceed into the parking spot. Left backing turns are easy because you can hang your head out the window and see most everything... Right ones are tough.
The problem with the first video, there are no trucks that pull doubles in this country, that look like that. That's a pure Ausie rig. The doubles you see here, like FEDX and UPS pull are a completely different deal. There are guys that can back doubles, and it's a special skill.
I drove a semi for 12 years, pulling flatbeds and double drops, but I had it easy, we had day cabs, so you could look out the back window on a off side back. I had many times the we were hauling bridge beams or large box culverts and had to back in a mile or more. Fun times.
When buying Enclosed Trailers, make sure to test before you buy. Place everything that you plan to haul inside of it on your driveway, but inside of the width of the Enclosed Trailers. Once you have it all there, measure the length that the stuff is taking up and then follow tip number 1.

The pivoting axles of these trailers are connected by a tie rod which turns the front and rear wheels in opposite directions. This design provides agile maneuvering of individual or multiple trailers in narrow aisles and around tight corners. A rear hitch on the four wheel steering trailer allows multiple trailers to track in the path of the lead trailer.
The Western Uniformity Scenario requested by the Western Governors' Association (WGA) from the Department of Transportation (DOT) is different than scenarios examined in the Comprehensive Truck Size and Weight (CTS&W) Study. Those scenarios focused on nationwide changes to truck size and weight limits. The Western Uniformity Scenario examines the impact of changes in truck size and weight regulations within a 13-State region in which all the States already allow at least some Longer Combination Vehicles (LCV). The States included in the analysis and shown in Figure II-1 are Colorado, Idaho, Kansas, Montana, Nebraska, Nevada, North Dakota, Oklahoma, Oregon, South Dakota, Utah, Washington and Wyoming.
While all the States included in the scenario already allow LCVs, most do not allow the weights and dimensions analyzed in the Scenario. In discussions with State representatives during the course of this analysis, some said that even if given the flexibility to allow heavier weights they would not do so. Thus it must be remembered that, like the scenarios analyzed in the CTS&W Study, this scenario is only illustrative of the impacts that could occur if all the States in the region uniformly adopted the size and weight limits assumed in the scenario.
Several Western States currently do not allow LCVs including California, Texas, New Mexico, and Arizona (except for a very small corner of the State). These States were invited to join in the scenario analysis but all declined.
The analysis includes a broad range of commercial truck configurations: five- and six-or-more - axle tractor-semitrailers, several double-trailer combinations with different weights and dimensions, and triple-trailer combinations. All these configurations are present in both the base case and in the Scenario, although not all States allow all the scenario vehicles in the base case.
The impact analysis in this report focuses on the 13 States in the study region. Table II-1 shows their road networks as a percentage of the national networks. This table shows that these States contain a higher percent of rural roads than urban roads when compared to the whole U.S. Table II-2 shows that within the 13 States more than 80 percent of the public road system is classified as rural. 1
The analysis year for this scenario is 2010. Forecasts of traffic by commodity, origin and destination, vehicle configuration, weight, and highway functional class are based on current conditions including current truck size and weight limits. Global Insights, formerly DRI/WEFA, developed economic forecasts and traffic volumes were forecast based on those economic assumptions. Distributions of traffic by vehicle class, operating weight, and highway functional class were assumed to remain the same as estimates developed for 2000, the latest year for which actual traffic volume data are available.
The base case for the scenario represents current patterns of truck and rail operations in the scenario States under current truck size and weight laws. It serves as a base line for estimating impacts of changes in truck size and weight limits assumed in the scenario. The Federal size and weight limits for the base case are shown in Figure II-3.
The base case includes the freeze on LCVs imposed by the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) that restricts the use of LCVs to the types of operations in effect as of June 1, 1991. The Transportation Equity Act for the 21st Century (TEA-21) continued the LCV freeze. It should be noted that there are two distinct freezes in the ISTEA, one on the weight of LCVs on the Interstate System and the other freeze on the length of the cargo carrying units of combinations with two or more such units on the NN. Table II-3 shows the lengths and weights of twin and triple trailer combinations that each of the 13 States included in the scenario may allow to operate under the LCV freeze.
* The National Network (NN) is the system of highways designated by the States in cooperation with FHWA on which the 48-foot semitrailers and short twin trailer combinations that States were required to allow under the Surface Transportation Assistance Act of 1982 (STAA) would be allowed to operate. Those highways were judged by the States to be suitable for use by those truck configurations.
Several States allow heavier weights off the Interstate System than are allowed under the LCV freeze on the Interstate System (see Table II-6). For example, Wyoming allows up to 156,000 pounds on a double-trailer, with the appropriate number and spacing of axles, on State designated, non-Interstate roads, but the freeze limits GVW to 117,000 pounds on Wyoming Interstate. The appropriate weight limit is considered for each road segment in both the base case and the scenario analysis. It is also assumed that no change in technology, operating practices, or relative pricing will take place between the base year (2000) and the analysis year (2010). Finally it is assumed that there would be no change in the TS&W regulations and VMT for any States other than those in the study.
Changes since the CTS&W Study include (1) updating the truck and rail commodity flow data and the distribution of truck traffic by configuration, highway functional class, and operating weight; (2) a detailed analysis of LCV operations in Western States; and (3) detailed analysis of the road networks on which LCVs currently are allowed.
