2010 3400RL or 2015 375FLF
This is my first post here. I have been reading through the threads for the last several days and decided to register and ask a few questions. I did search a bunch so I apologize if my questions seem like I am not doing my homework first.

The wife has decided that it is time to sell my older bumper pull and upgrade. We have two units we have been considering and I would like your input.

The first is a 2010 3400RL, it is in great shape and everything works well. It is being offered by the local RV dealership who I have had a great relationship with on past purchases.

The second is a 2015 375FLF from a private seller. It has the leveling system, dual AC units, the on board Onan as well as slide out awnings and many other options. It too appears to be lightly used and in great shape.

The price difference is about 17k. It will primarily use it for dry camping during the summer. Any input from owners of either unit would be great. Sorry for the long post.

Welcome to the forum. It will be interesting seeing replies in your question. My thought is from the year we looked. 7 years is a good cutoff due to the aging of unit - start getting into replacement period: tires, AC, Fridge, water heater - I gave up and went newer

NMIKE 08-28-2017 01:58 PM

Thank you for the Welcome and the advice. My current unit is a 2007 33' bumper pull and it has had very few equipment issues but construction was very poor. I am hoping that either of these models will present better construction than the Prowler I currently have.

Newer is generally a safer bet however a major factor is which floor plan the wife likes best.

NMIKE 08-28-2017 03:01 PM

The wife prefers the front living area that the FLF offers. I don't mind either of the plans as I spend most of my time outside. Thanks for the reply.

If the 2010 is a Hickory Edition you'll find some really well built cabinets. We put almost 60,000 miles on a 2010 3665RE and loved it. The floor plan on our new 2017 3720 is the only reason we gave it up. Someone got a great camper.

Chip 08-28-2017 04:05 PM

Are you going to travel with it much?

NMIKE 08-28-2017 07:22 PM

I hope to do some traveling in it but that will be dependent on how well I can free up time to get sweaty from work for a trip. The current unit we have is used once a year for a week at our rodeo here in Pendleton. I used to use it several times a year to camp in the mountains around here but it was never more than 100 miles round trip. I hope to make a coast run a couple of times a year which will be 700 round trip or so.

Since you are not traveling and using it very much the 3400RL might be the better deal for you. Of course the 375FLF has all the bells and whistles and is newer. Tough decision.
You didn't say what kind of truck you have, but both of these units are heavy so you need a truck that is capable of hauling and stopping them safely.

I have a 2014 375 FLF and really like it. Some problems, Norcold refergerator failure, water heater failure but overall nice unit. We full time in ours and it is seldom on the road. Overall it's a decent unit and when we bought it price was very good which helped make our decision.

NMIKE 08-28-2017 09:53 PM

I will be pulling it with a 2010 Ram 3500 with a Cummins, it is a manual with a new South Bend dual disc and pulls our horse trailers well. It is a long box crew cab. So the 3400 is at 29k and not negotiable but no options. Clean and hardly used, everything works well. The 375 is at 47k. It has the Onan on board, the awnings over each of the slides, the double fridge. He said every option that he could order short of having the factory add a washer and dryer. Is either of these prices a steal or about where they should be?

Mudchief 08-29-2017 12:45 AM

To answer your question on price Neither one is a steal. If you are going to use it I would go with the 375. If it is going to set and used very little I would go with the 3400.

I think you are answering your own question. :D

NMIKE 08-29-2017 11:16 AM

Thanks again for the taking the time to answer. I agree that the 3400 would be the best choice for how often we plan to use it. It does look like the happy wife happy life mantra is going to take effect in this case though. She likes the 375FLF and I am good with that as it does have some features that far outweigh anything I have camped in in the past. I was surprised to see it only has one battery. I will have to rectify that soon. I will also put some tires on it this spring after reading the tire conversations on here.

Thanks Lenny. It has taken me longer than it should have to figure it out so I am not so sure I am all that smart.

NMIKE 08-29-2017 04:51 PM

Anything I should really look out for when I go check it out from the seller? Like specific problem areas?

Rondo 08-29-2017 09:50 PM

Check for possible frame flex. You'll have to have them hook up the unit in front of you to see this. Also I think there is still a posting of the PDI (Pre Delivery Inspection) here on the Forum and that would be a good thing to have along with a flashlight to check out the dark areas of the unit also. Also, have the owner show you how to run the level-up system and make sure you get all the papers and manuals that came with the new unit when the owner got it. The tires are a really good idea to change especially if they are not Goodyear 614's or the Sailuns on the unit. The OEM tires are nothing but trouble whether you pull at 50 or 65 MPH. They will cause nothing but problems and could cause body damage if they blow. As you've kind of said "If Mama ain't happy, ain't nobody going to be happy!" and if she likes the 2015 model, that is the one to go with. You will really like the level-up system. I won't have anything without it anymore!

Agree, that's the key question. Newer with more stuff is better, if the D/W likes it, that seals the deal.

Ram Montana High Country 08-30-2017 09:03 AM

Rondo - you mentioned frame flex and visible when you hook up - where and what do you look for
