2007 Adventurer 38J information

Shopping for a used MH. I am looking at a 2007 Adventurer 38J with Workhorse engine and W24 chassis, Allison 2100 series transmission, 61,000 miles. Is this MH underpowered? This coach has several upgrades but I don't see any chassis upgrades. Anyone here have an Adventurer with a W24 Workhorse? Any information will be appreciated...Thanks

I had a 2010 Itasca Suncruiser 37F (Adventurer twin) on the W-24. IMO, no gasser is going to perform like a hot rod, but we had no problems going anywhere, including mountains, with it. The 8.1L and 6 speed Allison is hard to beat, but does not have the power and torque of a 450 HP diesel, nor the comfort of an air-ride suspension. Now where near the cost of operating and maintaining a large diesel, either. Choose you poison.

I am a huge fan of WCC gassers, and can tell you the W-24 series chassis are considered the best front-engine gasser ever built. NONE of them were involved with the "brake recall" you may read about. The W-24's brakes are larger and much more powerful than those that were used on the W-22s that were recalled. The 2000 series Allison is also more robust than the 1000 used in the W-22.

Unless you plan to travel extensively (LOTS of miles) and on mountainous roads, and spend more time rolling than camping, I think you will be satisfied with the gasser, and will most certainly do so at lower costs overall.

I agree with edgray’s comments-he is right on about maintenance, usage etc. We had a 2010 Suncruiser 35P on the w24 chassis with the Allison 2350 6 speed transmission. We drove it 55,000 miles until we sold it an upgraded to a Diesel Pusher.

I don’t recall the weight difference between the 35P and the 38 floor plan, but at worst it might reduce your carrying or tow capacity. A W24 in good shape is hard to find.

A couple things I experienced: 1) early on it developed a misfire. Turns out the airflow was insufficient and would burn plug wire on cylinder #7. Workhorse actually made an airflow kit to help. I ended up putting “racing” wires on to take the heat and problem solved. I got that recommendation from this forum. Another option was to install plug wire boots or sleeves. This was NOT an overheating issue at all as it always ran in the normal range-they have huge radiators on these. 2) expect it use some oil. I was ready for that as I had a 2003 Yukon with the 8.1 (same engine as the W24) and it burned a quart of oil every 1,000 miles since new until I sold it with 180,000 miles on the clock. Oddly enough the motorhome used about a quart every 1,500 miles, so a little less. It never bothered me since I had experience with the Yukon.

It was a great machine and served us well. The only system that might give me pause is the basement air. I never had any trouble but at the time others on this forum did. Finding someone with expertise with that system could be a challenge. Even the most expensive Class A’s have roof mounted a/c units.

I recall the marketing material at the time said the W24 was a 200,000 mile chassis.

Good luck

I have a 2005 Suncruiser 38J, sister to the Adventurer. I live on the West Coast and have driven across many of the major passes. It won't be the first one up but it will make it. In fact I normally have to ease off the gas and fall in behind the slowest heavy truck if there is not enough lanes for me to pass it easily (ie not blocking the only left lane). My model does not have the grade brake enabled (I think it became available by default on the 2006 model) so I manually downshift it to the gear that I want for the down grade portion.

The previous owner had installed a steering damper and a rear track bar and the handling is good. I am not sure how much difference those additions make but they are not too expensive to add if needed for sway control.

Mike

Thanks for the info, Mike. Any issues with the bottom air-conditioning?

I own a 2006 Winnebago Adventurer Class A model 38J with a Workhorse Chassis and a gas engine. I have had the dealer check for me and have found no re-calls or up-grades suggested. I might add that you might want to check the roof seams and see if they have been maintained as Winnebago recommends. I had the roof start to separate from the awning rail as I was traveling, luckily I caught it before it became catastrophic.

David: WELCOME to iRV2.com IF your 38J is on a W-24 chassis, the sixth vin # position will be an "A", and that means it isn't likely to have many (if any) recalls on the chassis, and it definitely was NOT subject to the "brake recall" that included ALL of the W-22 chassis. IF you want me to verify what the dealer told you, PM just the last 8 digits (only) of the chassis vin # that begins with "5B4". Ed

Hi Larry,

I had a small issue with the basement air. About two years ago I had one of the capacitors go bad. It was a pretty simple fix. I did pull the unit out and set it on a table next to the RV and did a cleaning and put some 3in1 oil on the bushings/bearings.
