FL60
I think if you take your time, and are patient, you can find a nice one. I got a Crew Cab FL60 (that is what the Mrs. wanted) with a Cat 3126/Allison 6 speed. It has a 17' flatbed with a gooseneck set up. I got it for less than 20 grand, and it is very clean w only 35K miles on it. It has two 75 gallon tanks, and air and cruise, so it isn't luxury, but the two air ride seats should make for a nice ride. I drive one at work quite a bit (1996 Biz Class, 8.3 Cummins with 6 speed manual-24' flatbed), but that truck is super loud. I am probably going to do lizard skin on mine for sound and temperature. I would have preferred the Cummins motor, but the 3126 is very good if you don't idle it for long periods-that is hard on them. Some have the 19.5 tires, but I like having the 22.5 rubber. We are mostly on road, so probably will not go with super singles for a while. I have 22.5 chains, and I believe it is easy to get lockers for these rear ends as well, and a winch never hurts...
I agree that it is a pain for tags and insurance. This truck weighs only 3,800# more than my 2500 Dodge, but the insurance companies act like it is hauling 80.000#...:Wow1: Darn thing weighs about 15,000 less than most Class A diesel pusher coaches, and Joe Schmoo goes down the road in those,towing an 8,000# Suburban, and the DOT, etc. are all oblivious because they fall under RV. Our 36' Foretravel has essentially the same driveline, w the 3116 Cat. It is tough to pull a gooseneck with it, so it is for sale. It weighs about 22k and gets a solid 11 mpg. USAA would not cover it either, but they have some type of deal w Progressive (which has my Boat and the Foretravel) and I got a commercial "farm" policy since I will use it to tow a gooseneck horse trailer, haul hay, etc. Runs about $500 per 6 months; I am a CDL holder since 1984 with a clean record, so that helps too. Mrs. NWNO wanted a "Sports Chassis", but I could not justify $70k for a truck with 160,000 miles on it to get leather seats, a dvd player and a hauler bed that I could not put a camper on... There was an M2 in town (Vancouver, WA.) this winter with an ext. cab. It was for sale for only $10k, with low miles, but it had the Mercedes motor and was having "communication issues" between the motor and transmission. It had a 28 foot box on it and a repair estimate of about 8 grand, but from what I have read, some of the MB motors have electric gremlins that can make you very sad. I guess I should have bought it for the value of the parts!
When I get my 'box' built, I will re tag it as an RV ASAP for the reasons stated. If you can't beat em, join em!
I am lurking on several build threads, looking at the best way to proceed (there are some whip smart people on here). In speaking to some of the builders, they get well north of $1,200 per square foot to build a true Expedition Camper. With an FL60, you don't need to be so concerned about weight, so wood cabinets will work instead of high $$ aluminum, and you can carry a generator, etc. I don't want a sticks and staples camper, so I am following what Total Composites and some of the others are doing. I like the cassette toilets, Wallas stoves, etc. for simplicity. You can also have Bolt make you a custom sleeper unit for your FL for about $45k, that would include everything you need, in about a 102" unit. I found a used unit like that for $1,000 that I could gut and redo, so there are tons of options, depending on your desires and $$$. My goal is to be all set up for under $80K, with about a 10 to 12 foot Expedition style camper, so I think it is possible.
