Can the welder be oriented side to side ,or is it too big? If it is to big use this template to re form your shape.template C you may endup with more a fish tail than a whale tail. Its fine to go past the tailgate and continue to reduce your wake. My V 2 will probably go 12-18" past, insted of my 8". Just account for opening the tailgate without having to pop the top and driveway angles when hooked up and loaded down for a move.

Can some one get the overhead view template C put in the tools link with the over lay feature of the side view (said looking towards the sky)

Its hard to make out with the trees but its 1/2"x.065"round with 1"x065" square edge. This is covered with 12mil industrial heat shrink wrap .. you could easily add an access door for the welder controls and cables. If you want a stronger more durable skin then look at Oratex 600 /6000. The 6000 is 1/2 oz./square foot. So named by the wight of aircraft certification in kilograms . V1.0 was 21lbs for the opening part ( White Part in sig) V1.2 is 35lbs (added ~20'of 1/2"x065 round and 1/2" foam insulation with mylar)

You stated that the welder is taller than normal to clear the gooseneck ball. Do you tow GN?

At first the wideband O2will teachyou when the computer is programed to do things like enrichment. You will see at what (") of vac.it goes rich. It may also go off how fast the needle moves. Your best mpg will b the result of maintaining the highest average vac. and the highest possible vac to maintain speed . The 2nd part is adjusting the throttle ever so slightly to account for even the smallest changes in grade.

OP questioned wether or not a 1ton was nessasary.
It sounds like a 1ton may be almost light duity for the lashings you give it . 3000lbs in the bed for welding gear on bord. And you leave home what you can! So this means that its probably closer to 4000lbs on bord +travel trailer. You have not stated any info on theTT just gussing from the TT in the pic . AC normally centered on TT so about 22' at 250/foot =5500lbs + gear. At 10% tongue weight thats at least 4550lbs load+ truck on thr rear axel without weight distribution system. The full of fule rear axle weight would have to be under 2500lbs for single wheel stock 245/75R16 are 3200ish lbs each.
Never guess with safety always scale the rig . Find out how much things change with and without trailer you could find that 550lbs tongue is closer ot 900lbs on the tires with weight transfer off the front.

Free spin hub kit. You have a center disconnect stock but everything is still spinning and that will burn fule. Just make shure to put it in 4x4 atleast one a month to keep the berings rotated and lubed.
