I tow a few different trailers with my 24’ 158” WB E450.
The tongue weight of a small utility trailer 12x5 aluminum shouldn't matter too much on a shorter WB 450 rv and if you towed a larger trailer , you could use a weight distributing hitch ad i did.
Towing both ways , i dont think i have noticed much difference regarding the front end feel while driving. At least not enough difference to go to a scale. It handles it all well much to my surprise.
The WD hitch was used on my 30’ x 7’ aluminum snomo trailer. That was between 3500/5000# all loaded depending how many sleds were on board. Hitch weight on that trailer is 12 - 13%. At weights above 3500 you can feel the towed weight more. Not that its bad, you just can feel that its there.
