First off thanks for such an awesome site!! I have scanned this entire site for two week's now.
So i run a youtube channel that my son and i go video these mud races. We have been sleeping in hotels every weekend this has literally drained every ounce of $$ we make thoe. We all ready need to haul our RZR's. So i am about to take the plunge on a 7x18 DIAMOND CARGO TRAILER.
My goal's are a shower located in the V, my fresh water tank under the axles?? my grey water for sink and shower under the V. (i will empty this tank when i get home) a sure flow pump somewhere and a Rheem hot water heater. The basic's of course insulation,A/c, fridge,2 window's,and I've got the factory installing an rv style door. At night I edit my video's so i found a wall mounted desk from lowes, will the thin metal studs hold this?? http://www.lowes.com/pd_432281-46935-WE ... facetInfo=

Thanks in advance Chris W
