A/c.. Home made!?

My VOLVO Car Hauler, used to be a day cab, its a 2001 VOVLVO WAH 64, I have a coffin sleeper on the back. its a short walk home after work..LOL.. Small sleep space , NO TELEVISIONS or Electrical other than a tiny light. THE Reson for my post is I just had a $140 three foot hose break that lead to my $300 plus compressor, that connects to my $500 this, n its conected to my $250 that... dad blammit! N I"VE HAD IT!! That stuff only happens on Weekends, it was 104 in St Louis that day, Come MOnday I found The HOSE was back ordered N i was over the road! GEEZE!! HAlf my motor is INSIDE THE CAB! So , I grabbed 10 bags of ice and 2 $20 FANS. n off i went. It was soo nice in that truck, N I shut my engine off at night.. then bought about 8 bags the next day. I was just busting them out spreading them on the floor over on the passenger side and around the gear shifter. Burying the fans.... WOW! N it cleaned my flooor real good too ....ANYHOW..... I'm contemplating throwing out the entire AC and HEATER system and replacing it with the following. THE PASSENGER SEAT will be REplaced by a Well insulated box - ICE CHEST. I can run air thru it using two $25 Blow dryers set on cool and provide more than enough cool air for that tiny truck or sleeper. I figure FIve bags of ICe a day in the SUMMER at $2.50 a bag vs ? THe wear n tear on my engine from running the AC and HEater system...plus 8 Gallons a night to run my engine so I can have AC? THe Insulation will dampen the noise from them when I'm sleeping so thats not a concern.. THE ONLY CONCERN is BATTERYS! I have 4 of them now, I 'm thinking I may need to run a higher rated Alternator?? and use a separate box with two GEL MARINE BAtteries in it. MY QUESTION is DOes anyone on this board know anyone that's gone electric without installing a generator. IF so howd they do it. Any Ideas or concerns about the set up?

 

Wow, forgot i posted this.. Anyhow... I did both.. Lol.. Cuz i got shammed into repairing my original AC, but was motivated to build this Thang by my unforgettable roadside nightmare brokedown in middleof nowhere upstate NY snow storm n all i could do is shiver n starr at 4 batteries connected to my blown engine!!
I gotta figure out how to post photos from
my i phone .. Till then ..check out campers websites for similar setups or.. Heres the specs...
I removed the passenger seat which is mounted ontop of a steel box frame bout ?? 14 in high.. Insulated it for sound n temps , drilled out two holes approx 1.5 diam. N mounted two $10 dollar store blow dryers.. I got a ice chest i set on top with a cheap radio shack computer fan pushing air into it two large holes with screen over them on the bottom to keep ice from falling thru ..., takes 3 bags of ice or two blocks ice shut my truck off every night , sleep about 5 or 6 hours n power is from my 4 battery bank .. I only run one blowdryer motor n the radio shack fan but so far my truck has cranked up every morning so?? No apu for me... Note: im in a day cab with a coffin sleeper n i got a curtain that cuts even that in half so... For u huys in the Condos?? Lol .. Dont even dream .. Lol .. Anyhow.. Thats the delio..
