Steerable wheels on cars and light trucks are limited to a 36-37 degree cut at full lock and a 90 degree turn will result in a truck to trailer angle around 45 degrees. Continuing to turn at full lock more than 90 degrees will result in contact. While an 8 ft bed is better, the problem still exists. Not staying at full lock for a complete turn makes a big difference. And as some understand, backing into a tight spot can still be done with a 6.5 ft bed/fixed hitch with a little extra jockeying back and forth. The extra time spent has the advantage of less stress on the trailer suspension/tires.
Travel trailers cannot be jack-knifed as sharp as the usual 6.5 ft bed/fixed hitch. TT owners don't have sliding hitches and can't see their point of contact as well as fiver owners. Yet they don't seem to have as many mistakes, or tire problems.
