Pilot reported off airport landing due to engine failure.

Narrative

Diverted to Jean; NV 0L7; due to high; unfavorable winds in the Las Vegas; NV area; especially at proposed destination VGT. Following a pass over Runway 02 to assess wind direction and effect on my light experimental aircraft; my engine failed on climb-out; necessitating a landing on a roadway approximately 1/2 mile north of Runway 02 at 0L7. [This was contributed to by] rushed; inadequate fueling and planning at departure airport ZZZ in attempt to get to destination before weather/winds worsened. Limited flight/operational experience in this light experimental aircraft. Did not have extensive experience in this aircraft nor available; adequate; aircraft operational data and fuel consumption on the experimental aircraft. [To prevent this;] better familiarity and experience in/with this aircraft operational and performance data. More thorough preflight planning including weather; other operational and environmental factors having the potential to affect the flight. Review and incorporate recommended operations at non-towered airports; i.e.; traffic pattern operations. More thorough review of and compliance with my aircraft operational and performance data and limitations. Assess my personal limitations and set and observe personal limits as appropriate to mechanical; operational; and environmental conditions. Thoroughly review regulatory and recommended procedures for operations in the NAS.Reassess and reevaluate the areas in my judgment and decision making processes that may have contributed to some complacency in this operation that may help me prevent a similar occurrence in the future. [This was] a [potential] failure in ensuring an adequate amount of fuel on board for the operation. Potentially a failure to become adequately familiar with all information pertinent to this flight operation; including; fuel on board; fuel remaining; weather; airspace issues; and airport operations.
