Hot Tub on the Roof - Would it work?

[johnny_mnemonic]

Got a 6' diameter inflatable hot tub (Coleman Lay-Z-Spa) that weighs around 2,500 lb, not including people. I'm told the roof structure of these buses (mine is an '85 Chevy C60/70 Bluebird) is quite rigid so as to stay intact in the event of a rollover, etc. Suppose I built a platform which distributed the weight evenly over, say, 3 or 4 of the roof's "rails" with perimeter support via 3 square tubes down each side of the bus past the windows, anchoring at multiple points. Would it take the weight? Anyone know of any studies (read: tailgate experiments) that really tested the weight limits of a skoolie roof?

[bubb, the real one]

I found one reference from the 80's, I dont not have the link, it stated that school buses must be able to take a dynamic load (rollover) with 1.5 times the buses empty weight, during the roll over the roof must not deform inward more than one foot.
ASSUMING this is correct you take the weight of the bus and divide it by the number of roof supports, this gives you a dynamic load, but I assume you wont drive with a full tub,

Welcome

Dunno, I want to see pictures though!

How to transport water?

Spread over a 8 x12 deck, and 4 roof bows supporting say 3600 lbs is 900 per beam...mm mm....still don't no.....

Still wanna see pictures, how you going to get main unfilled section up on roof each time?

Or just drain into barrells and ratchet strap down?

any progress on this? I am really thinking about doing it on my conversion

Just use light weight water. I've heard of "Heavy Water"...so there must be a "Lite" version out there somewhere.
