I extended out the rear bumper 10"s and the front support cross bar 10"s as well. My plan is to add 1" square back to the fender support put diamond plate on each side of the camper front and back of the fender. It can serve as a place to sit and I am thinking of mounting Jerry cans for gas and water for our Alaska trip later on. I am putting the entrance door in the rear off to the left side and two windows on each side of the camper. It is going to be a Caravan style with an angle on the front (tongue end) about a 1' down and 1' back. I will be added roof vent with fan as well. Later I plan to add an AC in the end next to the door up high so it will blow towards the front. The camper will be 5x8, 4' high with 3/4" birch walls. I am planning on making my own door, but I will be buying my windows. I plan to skin the outside with .040 aluminum with an enamel finish.
I love to build and after 40 years in the carpentry trade I am getting excited about building this trailer. I am retired and my wife is planning on retiring in 18 months. We are planning a month long trip to Alaska in our two door jeep and I am building this to pull with the jeep.
