No responses yet ?! I did consider it but the negatives out weighed the positives ( for me ). If you do decide, make sure you can access it to inspect it easily and adjust air pressure. A flat or under inflated spare will do you little good in an emergency situation on a lonely road!! Find a spot in the rear of your truck and keep on keep'n on !!
No, your response was the first. Thank for the reply. My main concern was the distance from a mount behind the rear jacks on the level up system, ( just behind the axles ) on certain uneven roads such as steep RR tracks.
