Yawn,
Used to do this daily with an equipment trailer, 1200 lbs of HW, and 10500 on the axels. Granted not an RV trailer, but wieghts are similar. I used to tow my TT which was in the 6-7000 lb total range, with 650-750 depending upon how loaded on the hitch with out bars too. I do admit, the rv trailer towed better with WD bars, better yet with a dual cam. BUT< the HW etc did not do too much to the 6400 lb RA on the two trucks I towed it with.
The ET on the other hand, does take more wt off the front, depending upon the WB, how much the front end weighs, overhang etc. So life can get interesting in some lower friction types of driving, like rain wetted roads, ice, the BIG slick WHITE cross walk painted area's etc. It is easier to slide with a lighter front end.
