wheelsea

trying a product that i found on line called hippo seal,,, says it will seal about anythingl, does anyone actually have any experience with this stuff? i can only hope it works i have a large crack almost 360 degrees around my gray tank where it fits to the pipe leading to the blade valve for dispensing, if it doesn't work can anyone tell me where i'd find a tank for such an old one off design such as this 86 sun land express ?? thanks and please reply

my 1986 toyota mh has a 18 inch extended rear for small items and such, my ? is can i mount my 200 lb scooter on its rack behind that, this will put my scooter's cg (center of gravity) about 30 inches from back of mh, could i use air shocks to help level the rv it doesn't sag much now but i'd like to use them without a lot of air pressure as not to put to much load on the mounts, also could i use an extra leaf spring instead or is there a way to rejuvinate the original leafs? thanks for any input from anyone with experience,,, oh yeah this is a 4 cyl. with auto trans, and i'm putting on a tranny cooler as well
