What Ohio asks of a build
Nothing here is about altitude. Towns in this guide run from 534 feet at Portsmouth to 1,245 at Bellefontaine, and the state high point is 1,550. What Ohio tests is water, mud and width. The forest that holds most of the federal land warns that springs are rainy, that flooding is common, that some roads have restricted access or close, and that its own designated routes may be unmaintained dirt passable only by a high-clearance vehicle.
Width is the second brief. A full-size truck is welcome on forest roads, byways and Corps lake camps, and it is too wide for both the Wayne trails at 50 inches and the state forest APV areas at 62. Decide early which of those two vehicles you are building, because the answer changes everything from tire size to whether you tow a machine behind you.
