Autotrail owners - spare wheel question

Gnash58

Hi all, the spare wheel on our Apache 700 SE is in the locker at the rear of the M/H. Underneath what is the rear lounge floor. Its far from easy to take out to check the pressure and or wash it. My question is - does any know if it is possible to have a
"mod" done so that the wheel is carried on the back of the M/H? (Where the cycle carrier fits). This would then free up space in the rear locker for a folding wheelchair and other bits and bobs. Cheers, Gary
