Is this a good idea?

DD will be getting her scuba certification soon and that means another gear bag, more tanks and generally more stuff to haul.  My idea was to install the "tracks" (can't think what else to call them) for a bike rack on the top of the P.U. and hook our turtle top carrier, soft-sided, to that.  When we put the turtle top on the Jeep, our MPG goes w-a-y down.  DH's concern was the added weight to the trailer.  

Your thoughts and ideas will be greatly appreciated -- I don't want to have even less space in the t.v. for us!

Of major concern will be the total weight on the bike rack. If this exceeds the recommended weight of the rack or the roof then there are potential problems. If the weight does not exceed either limits than it should be do-able. Ideally, an aerodynamic turtle top carrier would be the best bet. Good luck with this mod.

IIRC the max weight with the roof down on the ABS roof is 300# and with the roof up 100#.  That includes the weight of the rack, carrier, and contents.  If you have AC you will not be able to do this as AC is within 5 - 10# of 100# and the additional will put you over the 100# open weight.  I would also be careful loading up an ABS roof what with their tendency to sag.

Hope this helps.

Do not do this unless you have had your trailer on a scale.  It is all too easy to keep throwing things in and on today's trailers, never knowing just how overloaded it all is.

You can have 300 pounds on the roof of the PU closed and 150 pounds when it is open.  Even having the carrier on top of the PU will cause you mpg to drop.  I see a difference in my mpg when we carry bikes on the roof.  It is fine to carry stuff on the roof, but you have to keep your trailers weight limit in mind.  I carry the heaviest stuff in the TV.  I would put light weight stuff on top.  It makes it easier to get the stuff up on the roof and if something slips it will not damage the roof like a scuba tank would.
