Congratulations on the new trailer. Great floorplan!! Are you planning on using your 1/2 ton to tow?? I just looked up your trailer on Keystones website and see that it's 7800lbs dry and just under 36' long! I hate to be the barer of bad news but i'm afraid you will be over your trucks payload and possibly rear axle rating??
My trailer is 6500lbs dry and 32' long.I have the max tow pkg on my truck and i'm within 200lbs of my max payload even though i have a max tow rating of 11,200lbs which is unrealistic due to my lack of payload.
