Difference in levelers
I have noticed that larger DP models have hydraulic levelers, less large (39 & below) have electronic levelers. Is there anything to be aware of with electronic?

I think the reference was to stainless steel ram rods, not the whole unit. I have Lippert's hydraulic system on my coach and they had a real issue with hyd. lines being bubbled from corrosion inside the line prior to installation. IMHO Lippert products suck. So far knock on wood I've haven't had any problems. My 2000 Allegro had HWH. When it was about 8 yrs. old one seal started to leak on the left rear ram. At times it seemed like the springs for retraction were getting a bit weak but overall I prefer the HWH system from my Lippert. If you notice, a lot of the quality rigs out there like Tiffin use HWH.
Somehow, those hydraulic lines must've been exposed to some sort of extreme moisture to bubble as you described. That's certainly not good for hydraulic lines. In fact, moisture introduced into any part of the hydraulic system is trouble.
I haven't had any problem (knock-on-wood) with my HWH system.
Just to be clear, those rods are NOT Stainless Steel. They are solid steel chromed and polished rods. If they were Stainless Steel, nobody would be able to afford them.
They were made of stainless steel for many years however they may have changed in recent years. Here's a quote from a publication from HWH touting the use of stainless steel rods in the manufacture of their leveling jacks.
"Other manufacturers use plated hydraulic rods which can rust and pit, causing expensive damage to seals. Our stainless steel rods resist corrosion for many years of flawless operation."
