## Questions & Answers

**Q: Does this replace happijac 6100?**
A: 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.

**Q: Hello, do these jacks come with the brackets to mount to the camper frame? tia**
A: No they do not come with the brackets.

**Q: i have a 4160.  Would this replacement work with my existing remote?**
A: 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.

**Q: can these be easily removed for driving?**
A: 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit
*by T***R on November 17, 2024*

The replacement leg is just like the others. Easy to install.

### ⭐⭐⭐⭐ Replacement Jack
*by B***E on October 8, 2024*

Bought this to replace a 2002 Hapijac 4150 that failed. It did the trick, though I did need to file one of the mounting pieces on my camper since the lower bolt hole seems to be ever-so-slightly further from the upper bolts than the original. The manufacturer was helpful in selecting this replacement and sending specs. I wish they had included a top cap and a bolt. Overall, a solid replacement.

### ⭐⭐⭐⭐⭐ Perfect fit
*by A***R on May 24, 2023*

These jacks were a perfect fit to replace my older 4500 series they seem a little sturdier than the older ones they’re just a little pricey, but I’d rather spend the money and have confidence having a good product ,
