i think weight reduction will be important. when you do high speed long distance travle weight is less important, as it will basically act as a flywheel, but on slow, stop/go travel you'll have to accelerate all the mass of the vehicle over and over again and than wear out breaks to bring it to a halt again so, the more weight you can use the less fuel and breakpads you'll use. so considder what you can. evaluate the risk of leaving the spare tire home, or if with a little tinkering perhaps the passneger seat can we made to be swapped in and out with little effort perhaps...
