you got a set back axle trailer. i'm suprised the 'burb didn't squat with the load. you have a preload on the tongue weight. with the trailer and the ext cab you're hauling, you're OK in this combo to haul engine backwards since there will be little weight aft of the axles. your ext cab will have a rough gross of 6.8k. 4k will be front axle weight, the rest on the rear axle. if you load it backwards, the lighter side will be on the "bridge" between the axle and the tongue and the majority will be on the axles. if you secure the load with the pickup front axle right over the forward trailer axle, you "should" have a good balance there. if it doesn't feel right, some rearward or forward adjustment will make things right.
btw.....that's a nice trailer you have there.
i've been real lucky over the years, there's a truck scale around the corner from my shop that's open 24/7 and they don't care what you weigh after hours. as a result, it's been a good education for me on weights and balance and being able to estimate a load. When I was hauling for a friend of mime, I got hit with all the "O" loads......overlength/overheight/overweight and oddzised. the scarry part is the fact I was doing this at the behest of DOT, so no permits was needed. When you are operating in that capacity, you better know what your equipment can do and be smart about how you get things done.
