You got to be kidding me I was about to suggest this... Anyway I upvote since its a great idea. I wanted to add few stuff too like a weapon for Iron-miners. Here is a little example It will add more RP in the job and it could cost 1000$ in 24/7 shops. I guess it wouldn't be necessary to have it all the time on your hand when you work but when you get the job you could get it just like cops get nightstick. After you lose the job it would be removed.
I agree with you, to add those stuff, that will increas the RP, also I want to add the '' Dozer '' we don't have it, in CIT, so why don't we add it, in Iron Miner.
I thought that instead of sanchez, a mountain bike would be better because, sanchez being a motor bike costs fuel and even takes damage. I do agree that we got some ways in that iron mine for performing a stunt but having a mountain bike can "benefit players more" who are working in that job. For newbies in the server, a mountain bike would be highly beneficial as they wont be needing any money for repairing any motor bike and wouldn't even need to re-fuel their motor bike. We should think on this part of it as well.Anyways, I will support your suggestion, I really like it.
Upvoting because, It will be especially useful to be able to use a bike. You can quickly get anywhere like you said and it's just a lot faster. What if you are a higher level with that work and you also get better vehicles which able to use? As an NRG-500 just an example!
