Does this replace happijac 6100?

I replace a Happijac 4150 with a 4220. A perfect replacement, 15 minute total change out time. This was on a Eagle Cap 850 camper. If you are replacing legs on a camper, there is a list providing the direct replacements. If you are replacing a lift on a 5th wheel, I would be wary of this model number. I could only find that number applied to 5th wheel applications. The 4220 applies directly to the mounting bracket on my camper replacing the original 4150.hope this helps. I remember the confusion in using the references prior to my purchase.

Hello, do these jacks come with the brackets to mount to the camper frame? tia

No they do not come with the brackets.

i have a 4160. Would this replacement work with my existing remote?

The 4220 will, its a LOT beefier than the 4160, should bolt in the same...I would recommend talking to Happijak, their customer service is amazing and right there when you call.

can these be easily removed for driving?

If you mean removed from the camper I would say they are not easy to remove. They are heavy and not easy to line up. More work than I would want to do. I have replaced two of them myself. Was not easy.
