40' RV towing 20' car trailer

I am getting a 40' diesel RV and want to tow a 20' car trailer. What are some of the problems I may encounter with towing a trailer of this size? Parking in campgrounds? Fueling up? Is it common to tow something of this size or does it present too many problems. Any advise or suggestions would be greatly appreciated.
Thanks
  • Many states have a max allowable length of 65' and with this law there generally is no reciprocal privileges. That's mean if you're legal in your own state, you won't be legal in a state that has the 65' limit. Sounds like you may be right at 65' so you should be okay.

    Now having said that, I have seen many motorhome trailer combinations on the streets here in California that are clearly longer than 65' yet I've never heard of anybody getting a ticket for it. Doesn't mean it still isn't illegal, it's just one of those laws that doesn't get a lot of enforcement when it comes to RV's.
  • Hello,
    We are considering the purchase of a 2007 Damon Tuscany Diesel Pusher. It has the Cat 350 for power. This coach does not have a tag axel. It has a 10K receiver hitch.
    I'd like to know if anyone routinely pulls an enclosed trailer with either a vehicle or four Harleys in it. I know the tag axel lends stability and certainly improves the ride, but I'm curious about the single dually axle characteristics. Thanks
  • We have no problem at all towing a 20' enclosed trailer. Hardly know it's back there. Usually have 4 quads and 4 dirt bikes but have stuck the jeep in there at times as well. mp
  • How does your coach react with the trailer when over taking a semi or passing by an oncoming semi on a two lane road?

    Our previous coach, a 38' Beaver Contessa, did not have a tag axle and towed a 24' enclosed trailer well. I used a weight distributing hitch and it handled great, a little low on power but it had the 3208 CAT and a four-speed Allison transmission. We drive it over most of the western U.S. for 7 years.

    Straight as an arrow. No side to side movement whatsowever. With a large, and I mean large, crosswind sometimes I will feel a very slight movement but rarely do we get moved around by wind. That is primarily due to how heavy we are. I prefer to travel the two-lane country roads vs. interstates anyway just for the scenery.

  • I tow a 32ft enclosed behind a 38ft DP and have for several years. 325 Cummins and 6spd Allison....this thing is really heavy yet goes over the mountains at 55, never any side movement and I usually drive 70 or so on the interstates. I have had this mess in about every state East of the Big river with no LEO problems.
  • Thank you all for the reassurance. I appreciate the feed back.
  • Use to drive big truck awhile back and have run into over length issues on past occasions. I've spoken to a number of LEOs and although there are states with lenght restrictions, most will not issue a summons unless there is an accident with an overlength vehicle. Then they will give you a summons.
    They (the summons) are non point accurring with a $ fine. "Don't worry be driving!"
  • We routinely pull an enclosed car hauler (Haulmark) behind our motorhome. As other posters have mentioned, its almost easier than flat-towing a car because you can back up it with no problems. My recommendation is that you make sure the trailer you get has an "extended tongue" which is a little bit longer than the standard tongue. It helps prevent pinching the back corner of the motorhome against the front corner of the trailer during tight maneuvering situations. As one poster mentioned if you can get by with an 18 foot or 16 foot versus a 20 foot trailer, it makes it a little easier to fit it into shorter parking spots. We use a weight distributing hitch (Equalizer 4-way) and have been very pleased with the handling and stability of the trailer even in high cross winds. Also, since the hitch does not use chains or friction stabilizer bars, it works well when backing with sharp turns into tight parking spots. Finally, a great reference book I heard about on this forum, and use regularly to help plan our trips is called "Big Rigs Best Bets". It lists names of campgrounds by state and provides specific site numbers and lengths and tells which ones can best accommodate big motorhomes with tows. I think its laso available in an online version. Check it out.
