My mum uses a walker , i think it is a rollator brand , i cant remember for sure , i just went with her , found one that suited , bought it .. this is pretty much it , but mums is red , red ones go faster ya k now
Yeah i hijacked that image its not mine
I use it when my back gives me grief too tho .
I have issues with disks in my lower back , between shoulder blades , and in neck .I had a couple incidents at work .. long story but it leaves me with problems getting around at times
for me , its not about lugging more gear tho , its about being able to do more , with less , and working inside my limits .
I do weigh in at 100 kilo , or 200 pound i believe it converts to , but i stand at a shade under 6 foot 5 when i can be properly upright

.
we live kinda rural here , and fire and flood are real concerns every year . while we not planning for zombie invasion , or orcs , or anything romantic yet , we do prepare for getting out if the roads are cut , if the local town is cut off we moved to the next one up , we have friends there who will put us up without hesitation , if we have to go further , we have plans for that , we in turn are ful ready to put up anyone who need it among our friends too .
getting around with a walker meant re thinking my old habits , no more easily walking along stock tracks or following easily tracks that are just two wheel ruts in the dirt , it has led to experimenting with alternative motorized transport tho , electric wheel chairs and shopping buggys are OK , but they take long recharge times , and have limited range .. i have been using a re purposed ride on mower tho instead at times , when i run out of fuel i fill it from a can and keep on going no parking up next to a power point to recharge for 8 hours
its meant using a quad bike more when i go bush , just a cheap chinese one , no speed to it but its low geared , suits me fine , modded the handle bars to mean i dont have to lean forward so much , andit works well , for me
just some ideas and options that may help out , hope it all goes well for you
