interested in pam/decker. any info appreciated

Hi! I am new here and just put app in with driver's solutions and received booklet of information for all of their companies. I am thinking about going with decker but i am afraid to start too late in the year because if i get hired i don't want to face the winter with little or no experience.
The other thing is i've been employed with a company now for 15.5 years and the pay is good but business is not. Working only 4 days a week and bills are piling up! I have so many questions but don't know where to start. I am excited about starting a new career but apprehensive too because i don't want to walk away from a job to end up with nothing!
Also are there any policies regarding appearance? Right now i have long hair down below my shoulders and don't know if i should get it cut if i decide to go for trucking. I am a musician hence the hair but i've had it short before but don't want to cut it unless necessary. My only other concern is dot physical because of my vision. my 1 eye was bad but now i got a contact lens and can see perfect,but i don't know what my vision is in that eye. my other eye is 20/20 and my total vision is 20/30 or 20/25.
Everything else i have no worries. don't drink,smoke or do drugs! never have never will! Thanks and sorry for long winded post.

 

Thanks to all your replies. I hope you don't have wrong image of me or if i was misrepresenting my appearance. I shower every day as well as brush my teeth 2 or 3xs a day. I usually will wear a ponytail or put hair up under a hat. I'm basically just on of the ones from the 80's so its harder to shake the look and the music.lol! I did have short hair for awhile and came to realize it wasn't me it just took forever to get it to grow lol!! I'm not in a band as of yet but have been playing lead guitar for 23 years. I am a child of the 80's and love that eras music of all kinds except rap! i also shave every other day because i don't like having a beard at all. i was just wondering how it is out there because of my hair even though i've seen many drivers with short and long hair since i deal with them at my current warehouse job. I will say most of them are very polite and nice and if have time have plenty to talk about or answer any questions i may have which is very cool! I met one lady who was a trucker with her husband and asked her about it and she was helpful and made me laugh! she said"Honey if i can drive one of these things and do it like i do every day anyone can do it" made me smile and brightened up my day. I just know certain jobs frown on people with long hair and they won't hire them. Like i said though i don't have problem with cutting it but if i don't have to why bother. I take care of myself and always try to take pride in how i look but i know long hair can sometimes turn people off so i was concerned and didn't want to convey a wrong image,even though i don't always care what people think. The other thing i forgot to mention was last year i got my motorcycle license and because of my bad eye they gave me 2 restrictions on updated license. the restriction was i must have 2 mirrors in order to drive anything. several months ago i went for cdl permit with hazzmat and they also told me i passed vision however i may not make guidelines for hazzmat but that was before i saw an eye specialist and got a specially made lens for my bad eye. with the new lense my vision improved drastically. i know my total vision is 20/30 or 20/25. my bad eye used to be 20/70 but with lens i remember being able to read 20/50 but i don't know what toal number is for that eye but i should be o.k. i think i will call them and see if they can pull my records and let me know. I already told recruiter if i leave for their school i can't come back empty handed because i will lose my current job and he assured me that won't happen but i know not everything is the truth. lol! Thanks all and i will keep in touch!
