See fiver in sig. Cap to Cap is 40'6 in long. Official measurement is 38'11' That is pin box to rear cap. I carry two bikes which makes the fiver about 43' long for the sake of finding spots. Most parks have more then enough overhang room. We full time and stay in state and federal parks the majority of the time. You will find parks mostly government that will not accommodate you. However there are many more where you will fit. Be advised that DRV is a heavy rig. You will need a diesel dually at min.
