I've gotta tell you that you have kicked in some great memories.
I didn't graduate to my 2006 LBZ until 2009 when my son's were finishing high school.
We managed to survive with a '99 Ford F150 extended cab with the 4L v8.
Skiing, fishing, backpacking and loving the Rockies.
Yer tugging on my aging memories.
Enjoy and take care, my sayings from back in those days:
I like my truck and car but in the end they are just crates for the important eggs that are inside.
Don't rush your maintenance, it will work out over time with persistence.
Budget some $$ for an unexpected situation and just do things as you can.
The advice I've seen on this forum is great but no need to rush it.
Deal with it as you can, there are preferred priorities and real necessities, Know the difference.
And best of luck to you and yours.
