Front hitch

I don't consider the extra weight to be of concern as it's over and done in just minutes and it's not a catastrophic overload.
Maybe some extra wear but I did it for years after ever camp to park at home and the front suspension is just fine on my 2007 with 200K

I have been looking into front hitches, which actually are mostly used for snow plows, and the downward weight limit on most of them seems to be 300 to 500 lbs. So personally I wouldn't hook a TT to a front hitch, unless it was a very small and light TT.

In addition to the reduced visibility, I don't think I'd want to drop a trailer onto my front suspension like that. At least without doing some serious math first. Though I guess some trucks are setup for large snow plows that can weigh in about the same as the tongue on a larger trailer.

If it was a boat that you were positioning that you can see over or around, that would work. But with an RV, you're not going to see around it at all.

At least backing up, you have two mirrors that are as wide or wider than the RV you're backing up. With a front hitch you're going to be sitting there staring at a big wall 6 - 8' in front of you that you can't see over or around. I think you'll have less viability overall than you do with the mirrors backing up.

It's harder to see around the blind side, in fact impossible.
That said if you're familiar with where you're backing or scope it out good you can back into a very tight spot.
