Under 2 is typically "good enough" but with a little tweaking, usually at the mount, it's usually possible to get down below 1.5:1.
You're not using an NGP (no groundplane) type of antenna are you? That type of antenna does not work very well on a Jeep (or anywhere for that matter) and it can make getting a low SWR difficult.
What type of antenna mount are you using? Is the antenna mount getting a good sold bare metal-to-metal connection to its body mount? Is the body mount getting a good solid bare metal-to-bare-metal connection what it is attached to on the Jeep? A good solid bare metal ground connection between the right part of the mount & the Jeep is critical to getting a good low SWR.
Can you take a good close-up photo of your antenna mount? One additional photo from the underside of it would be helpful.
