These are my 2 vehicles and chase in both of them but for totally different scenarios. They are a 1996 Silverado K1500 with a long 8 ft bed and a 2018 Jeep Grand Cherokee Trackhawk.

The truck is the work horse that I'm not afraid to take a bit of hail on and push into the heart of things. I've spent a ton on fixing it up and is highly reliable with its simple 5.7l small block and a newly built transmission. I really only have room for 1 other person to ride so this is usually my chasecation option. It's got a full mattress and tons of camping, recreation, and chasing equipment so makes long trips a breeze, quite comfy, and down days quite fun. The camper shell is super cheap and can take a beating and the windshield is quite primitive and easy/cheap to replace, so tend to push this one.
The Jeep is a fire breathing bat outta hell and is powered by a 6.2l supercharged V8 producing well over 700 HP and clocking a 3.1 0-60 time. I'm much less inclined to core or RFD punch in this thing since it's a much more expensive vehicle to maintain and fix up. This is used for shorter trips <3 days and try my best to keep it out of hail. I try keeping escape options open, viewing from a further vantage point and getting into position faster. Obviously that is the idea, but things change rapidly sometimes. This thing is an absolute blast to drive out in the more empty western chasing areas (CO, WY, NM, SD, etc) where there are long stretches of totally empty highway to punch it on. It makes those areas far more interesting and fun to be in as it can get kinda boring sometimes and allows me to make great time. Further east and it's a bit less fun because it's more developed, with more traffic, and less sight line so it can tend to be an exercise in patience.
I love both of these vehicles for different reasons and don't really have any plans to change them anytime soon.
