Right now I have a 2005 2wd Nissan Frontier. And i am planning on switching to an 4x4 s model. I would buy the off road model but there is no way that i can afford it. My frontier has a rear locker, so 2 wheel drive. And the x has 4x4 but with open diffs. So techqunequly also 2 wheel drive. I was wondering if iam going to notice significant differance off road. and those of you that have the s or se model how often do you have only 2 wheels spinning. Cuz in my truck withougt the locker on its basicily 1 wheel drive most of the time. Thank you very much for any feedback.
