This is totally personal opinion and we have the 2552 so it isn't exactly the same as finding level with the 2350 but I would totally vote for the levelers. We have been full time for a month and a half and have camped everywhere from paved pads to crooked parking lots to mud holes with "gravel pads" (that's a generous description). We haven't even hit the National Forest sites yet. We love our levelers. They won't get you level in every situation all by themselves but they sure get you there most of the time with minimal pain and effort. We watch other campers setting up and leveling and repeatedly say how happy we are that we don't have to do that. I watched a couple last night setting up a travel trailer on a questionable gravel pad. The brave wife stood in the rain in ankle deep water and mud in the dark holding the flashlight so hubby could back it in. They then spent a good 20 minutes trying to level her. I've seen fancy plastic blocks, huge wooden blocks (where do they carry all that?) and what looks like stacked firewood, all in an effort to get somewhat level, often still sitting at a tilt. We pull in to the most level section of ground we can get, set out the jack pads if we are on soft ground, then drop the jacks and level... all in minutes.
As for the 50 amp, we have had tripped the power a few times due to turning on the microwave while we have the AC on. We've pretty much learned to turn the AC to fan only, nuke the food, then turn the AC back on. We don't usually microwave for an extended time so it works. We don't know if you can use the convection part of the stove with the AC on when running 30 amps. Maybe someone else will weigh in with the benefits of 50 amps. I know some get it and add a second AC unit but I think that would be overkill in the 2350 unless you plan to camp REALLY hot areas for extended time.
So, that's my two cents worth. Hope it helps. Enjoy your factory tour and your new PC. We've had a few break in problems but LOVE ours.
