teardropsleeper - I added the additional tongue piece mainly because I couldn't abide the looks of the HF factory coupler mount. You'll notice in the pic that the factory mount is simply a trapezoid plate with a 2.5X2.5" piece welded on that the coupler bolts on. Looked like hell to me, besides with my profile the floor extends about 7" in front of the steel frame & the front wall curve another 4-5" so actually the original coupler mount would have been too close to the trailer body. I simply unbolted the factory plate, turned it upside down (after some judicious grinding to make it fit

) & bolted it to the original A-frame tongue. I then took a length of 2X2X3/16" square tubing, cut to proper length, bolted a pair of 1.5X1.5" pieces of angle iron to the two front cross members of the trailer frame, placed the new tongue piece thru the old factory mount & between the angles, & bolted everything up, after squaring the tongue to the axle hubs. My new tongue puts the front of the coupler exactly 45" away from the nearest part of the curved front of the trailer body. Here's pix of the original mount, & the new tongue installed -
Sierrajack - Actually I didn't use any liner for the wheel wells yet. So far I've just used the SBS (sticky black stuff) asphalt roof emulsion & it's held up well for the approx 1500mi I've pulled it, mostly over freeway but also quite a lot of 2-lane, hilly, rough, blacktop roads. I'm waiting to see how much mud'n crud gets thrown up there & sticks 'fore I decide what (if?) kinda liner I may put in. I have some strips of flexible fiberglass 'bout 3/32" thick that I may try if it looks as tho I need it

. As for the front (& rear) floor overhang, my entire floor, frame, side skirt, floor, etc., is made as a sorta 'truss' unit. Everything is tied together with PL construction adhesive, screws, & 2" construction staples, then bolted to the steel frame with ten 7/16" galvanized carriage bolts. My front overhang is around 7" & the rear is a little less. The inner walls & frame were fastened to the floor frame thru top of the floor, again with PL adhesive, 1/4X4" lag screws, & a dozen or so #12X4" deck screws, before adding insulation, & then the outer wood wall sheathing was glued/screwed/stapled to both the wall frame & the 'skirt' board before the final aluminum skin was added. No Jack, I've never built a TD before altho I have built a couple of cabover P/U campers. I know the stresses involved in 'cantilevering' the cabover section & the 'wings' that extend over the sides of the P/U. I'm pretty sure I allowed for that in my small overhangs here
