Hi Daniel - There's a couple of problems with the laser you're looking for - It doesn't exist.
The moon is incredibly far away. 400,000km or 248,000 miles. The kind of lasers that astronomers use to hit the retro-reflectors on the moon is highly specific to the job at hand and will probably have cost tens if not hundreds of thousands of dollars. The reason for this is that to hit the moon - you need a laser with a very low divergence. No handheld lasers are good enough in this regard - as their beams spread out too quickly.
This effect is noticeable for many lasers, especially powerful multi-mode diode lasers, and the beam will noticeably spread out from one side of a large room to the other. Imagine how wide that beam will be after 248,000 miles... Forget this part of your request and then it becomes more realistic. You can point at things that are far away if you equip a laser with a Beam Expander - which widens the beam, but in the process reduces the divergence. I.e. the beam starts wider - but it won't spread out as much.
Green lasers fall into two categories, Direct-diode and DPSS. Direct Diode lasers consist of a laser diode which emits green light directly, and DPSS uses a series of crystals to change Infra-red light into green. DPSS lasers are generally cheaper nowadays, but you will get a very varied mix of power from them depending on temperature. Additionally - Lasers are fragile - if it "rattles around your truck" it's going to break. Put it in a pocket or padded case somewhere inside the truck and you should be fine.
A list of good and bad companies to buy from is listed in
this thread. I personally have good experiences with Sanwu, but JetLasers are also well-regarded here. I honestly reccomend buying a cheap mass-produced 532 to dip your toes in and see if you want to spend more on a properly made one. This should be no more than $5-8 on the likes of Ebay or BangGood.
Before you even think about buying a laser - You MUST equip yourself with suitable eye-protection. Lasers are dangerous and can cause bad eye damage, which can be mitigated by wearing laser goggles designed to block the specific colour of light. Sunglasses/Welding masks etc are NOT suitable and will not protect your eyes.
