Welcome!
I was in the same boat a couple of months ago. I play drums as well in a gigging band. Loud rock and roll, INFINITE FLUX. I have a large Ludwig 26x14" bass, 14x10" rack, 16x16" floor, and 14x6.5" snare. I am also playing fairly large cymbals Paiste 2002 line, 24" Ride, 15"SE hats, 24" Reverend Al's Big Ride (right side crash) & 22" Crash. This is, exactly what made me decide on a Runner. I can easily fit all that in cases along with a medium size SKB hardware case. For the most part we cram all our gear into an "A-Team" themed van and head to shows. But, it is nice having options to cart my own stuff around and have it be safe.
I have a 1994 Toyota Extended cab, but I didn't want to get another canopy to keep the drums safe from the elements and thieving hands. I think if you find a good T4R, it will treat you much better in the long run compared to a Jeep.
I picked up a 2002 4Runner and I am really digging it.
