[Hitch Mounted Cargo Rack?]

In a nut shell, is a receiver hitch mounted cargo rack a viable option on the rear of a 1991 Itasca, V6 with rear duals?

I worry about that long overhang and if the receiver ( 2") and body framework can take 2-300 lbs on the back.

Your comments and advice would be gladly received.

Thanks!

[Gas Tanks]

I have a 1991 Toyota Itasca, 6 cyl with 120,000 m on it, and in very good shape if I may say so!

I note that in reading the Toyota manual that my gas tank has a 13 gallon capacity which, given my RV travel plans, is very modest. Given where I will be travelling, I do not expect gas stations as often as here in Canada or the US.

I found an online supplier who offers 17 gallon tanks for this vehicle which sorely tempts me as I am a bit reluctant to put 10 gallons in Jerry cans on the back bumper.

Has anyone had any experience in putting in a bigger gas tank? Any advice?

Many thanks!
