Peterbilt 350 WIP 6 (Patreon)

Hey guys - here's the latest WIP build of the Peterbilt 350. It's very close to being a functional mod: 

- the interior is progressing very well
- the windows are set up for rain
- I've started rebalancing the accessory prices and levels,
- only a few things are still missing shadows

With some finagling, the player can buy it for ~$25,000, making early-game truck ownership very attainable. The tradeoff is that the low-level engine options make gearing in the mid 5.00's necessary for heavier gross weights, and thus limits the truck to 45-50 mph top speed.

Currently, I only have double reduction gearing set up (so the lowest final drive is something like 4.67). What I want to do is have separate chassis options with SQHD rears that the player will have to level-up to and buy before they can have faster gearing. The trouble is, I'll need to model another suspension and axle set to do this. So my question to you guys is: Would it kill the initial release if the truck has 4.67 as its fastest gearing option?
